Don't use select() if possible. You don't know which direction is required
for a file descriptor. You must use snd_seq_poll_descriptors_revents()
which mangles the used direction and reports the correct one to
the application (and yes, it might be an opposite or both
directions in real if we implementing some complex devices behind this
API).
