poll uses select(2), while poll2 uses poll(2) (duh, that's confusing).
It seems that on OS X Snow Leopard, poll(2) sets the POLLPRI flag upon EPIPE (and probably doesn't return the FD in the exception set for select(2)...).
Not sure whether it's legal, but it's the only OS to do that (POLLPRI usually used for OOB data). Also, note that Tiger doesn't behave that way.
OS X often offers such surprises :-)

I just added an handle_expt() handler, and it works fine.

Closing, thanks for the patch!
