We have a highly regarded answer by nohat to a question about gender-neutral pronouns, in which he points to the "singular they" and its long history of use in English. (Note that he also advises against using it.) Example:
If someone wants to watch TV tonight, they'll have to do the dishes.
This avoids having to say "he or she" in mixed-gender situations. Okay, fine. I'm not going to get my panties in a bunch if people want to talk this way.
But it occurrs to me that "singular they"—infelicitous at the best of times—really falls apart when extended into the realm of reflexive pronouns:
If someone wants to watch TV tonight, they'll have to do the dishes all by themselves. [?]
That feels very wrong. The only alternative, if one paints oneself into that corner, is to flip it back to singular:
If someone wants to watch TV tonight, they'll have to do the dishes all by themself. [???]
That feels worse.
If I'm to state this as a question, I guess I would put it thus: How can use of a "singular they" truly be reconciled? Is it really as much of a linguistic dead end as it feels to me?
Best Answer
“Themself”
Themself was used in the past, and there is no law or authority that prohibits anyone from using it today. I have used it in personal correspondence, conscious of its rebellious and contradictory nature; however, I have to confess many of my correspondents are in the field of language teaching, and they tend to be more open-minded.
Although the singular themself is gaining currency, it would be an arduous challenge for anyone to produce a recent government bill, act, tax form, or any official English document that contains the actual reflexive pronoun. And if they could produce a formal document, it would be akin to seeing an exotic and engendered butterfly in the wild.
It's simply not done; not today, not in a formal context simply because it looks “wrong”. Themself looks dialectal, a word that an uneducated native speaker person might use. While the singular they, their and them are extremely common in speech—and increasingly so in writing as it avoids having to write the cumbersome he or she; his or her; him or her—yet many English native speakers consider themself not a “proper word”, and whenever instances of ourself and themself appear in writing, these words stick out like a sore thumb.

Themselves
An Ngram showing themself tells us that it existed and exists. An Ngram that compares themself and themselves reflects its usage more accurately.
Him(self) or herself
An Ngram that compares themself (blue line); himself or herself (red line); him or herself (green) and herself and himself (yellow) tells us that the majority of writers (and editors) feel more comfortable using a longer equivalent than the succinct themself.
On Google Books, the politically-correct expression, "herself or himself", produces around 1,480 results. Here are some examples:
1963, Standard Civil Code of the State of California
and as recently as 2009, Code of Federal Regulations
Whereas himself or herself gets 8,190 hits

Interestingly, the authors use the impersonal pronouns it and itself when referring to babies and small infants on page 58.
In a formal or technical register, himself or herself, will usually be preferred. And it seems highly unlikely that it will change in the near future.

And those sitting on the fence
In 2013, Catherine Soanes, guest blogger on OxfordWords blog, and one of the editors of the OED 2nd edition 2005, argued:
If you dislike using “themself”, what can you do?
The OP's example:
Sound perfectly acceptable to my ears. In speech and in an informal context, it is perfectly fine. For anyone who dislikes this solution I would suggest the following:
If I am speaking to more than one person
or to any individual, male or female
or you could try this "clunkier" version
If I had to use this particular construction, for efficiency's sake, I'd choose him or herself, which is well-documented and represented by the green line in the third Ngram chart.
