I'm happy to check if my bits still work if it's not too much hassle
to go back and forth.

Well there's not *nothing* we can do. I thought I we were going to
have to go back and do manual offset calculations to get that right.
But with the u64_t element that's probably not necessary. It's a bit
scary having that be the only thing protecting it but then again it's
probably exactly why it's there. Given how much of a pain doing manual
offset calculations I'm happy to go along and say it's not worth
bothering.

Should the maxaligns be there for the non-epoll cases? I tossed them
in without paying much attention. I really have no idea if they're
needed on Windows or not for example.
