output to send a SIGIO signal to the running program. However, we don't
handle this signal anywhere in the code, so setting the option is
unnecessary.

If anyone knows more about O_ASYNC than I do, please speak up, but doing some
reading and research leads me to believe I'm not lying in my commit message
above.
>From the manpage:
If you set the O_ASYNC status flag on a file descriptor by using the F_SETFL
command of fcntl(), a SIGIO signal is sent whenever input or output becomes
possible on that file descriptor. F_SETSIG can be used to obtain delivery of a
signal other than SIGIO. If this permission check fails, then the signal is
silently discarded.
