Considering that we know that major platforms
such as FreeBSD have changed their implementations *very* recently,
it seems foolish to assume that an executable built on a machine with
corrected pselect could not be run on one with an older implementation.
FWIW testing a recent development (i.e. 9.0-devel) version of FreeBSD
still failed to properly support pselect().
Also, we have plenty of experience with substituting poll() for
select(), so I'm not too worried about copy-and-pasting such code.
It's certainly a simpler change than the self-pipe trick vs. pselect(), yes.
I'm happy to go with the self-pipe trick. A quick micro-benchmark didn't
even show any significant difference compared to pselect(), so form that
perspective, it's not a big deal.
And we'd then have a major project using the self-pipe trick. (I would
still like to know what others exist).
