Well, it's not defined in the Single Unix Spec, which is our customary
reference for portability. Also, it's alleged that some platforms have
it but in a form that's not actually any safer than select(). For
example, I read in the Darwin man page for it
IMPLEMENTATION NOTES
The pselect() function is implemented in the C library as a wrapper
around select().
and that man page appears to be borrowed verbatim from FreeBSD.

It's just two handles per process.
