Note that the poll emulation in xnu was incomplete the last time I
checked. Granted, that was 10 years ago so it might be better now,
but at the time you couldn't poll much more than sockets. I got
burned trying to poll tty devices which simply didn't work. The
select system call doesn't use kqueue as a backend, though.
According the the man pages this is still the case:
BUGS
The poll() system call currently does not support devices.
