I didn't look closely enough into the internals to see what this is
actually doing. but when you refer to AIO are you referring to some
feature of the usb stack that queues up requests and then indicates
that they have finished, or the more general aio_read() functions?
IIRC the latter use a thread to do a synchronous read since normal
unix kernels are not designed to async io. The threads might be a
limited kernel resource.
