These patches convert thread-pool.c from EventNotifier to QEMUBH.
They then
solve the deadlock when nested aio_poll() calls are made.
Please speak out whether you want this in QEMU 2.1 or not. I'm not
aware of
the nested aio_poll() deadlock ever having been reported, so maybe we
can defer
to QEMU 2.2.
It was reported as a hang in block_commit. Marcin, can you please test
these patches?
I try to test it tomorrow. The same hang was also in linux-aio however
(I was able to reproduce it).
