(Correction to earlier: POLLHUP|POLLOUT is wrong -- the two bits are
mutually exclusive in POSIX (and have been for a while, I think):
https://pubs.opengroup.org/onlinepubs/9799919799/functions/poll.html
So Linux is wrong to return POLLHUP|POLLOUT|POLLWRNORM, and NetBSD is
right not to include POLLHUP, in one of the test cases I checked.)
