Try to open /dev/null, and then to poll the file descriptor. Neither in the
man page nor in the standard I see anything preventing you to poll on
/dev/null, yet, it does not work on Mac OS X. You get a POLLNVAL.

As it stands now, it looks like the only reason for POLLNVAL is a closed
file descriptor.
Sorry and thanks.

poll(fds)
for fd in fds:
if fd.revents | POLLIN:
fd.read_callback()
if fd.revents | POLLOUT:
fd.write_callback()
Now let's say I want a fake
