Otherwise, the read end of a fifo might return that it is writable (which it isn't). Only poll the fifo for write events if the fifo attached to a writable file descriptor. Otherwise, the write end of a fifo might return that it is readable (which it isn't). In the event that a file is FREAD|FWRITE (which is allowed by POSIX, but has undefined behavior), we poll for both.
