Leading to: why would (real) signals being used to collect AIO events
anyway, if you don't have signalfd()? If you've got a helper thread,
just call aio_suspend() in the helper thread.

 Then you can just
deliver the AIO completion result to the relevant data structure or
even move it off the waiting queue (pthread_mutex_lock is your
friend), then wake the main waiting thread with byte written to its
pipe.
