there is a problem in ubd / aio on host 2.4, that I can
I inserted some counters into submit_aio(), not_aio_thread()
and ubd_intr(). If the problem occurs, both
submit_aio_24() and not_aio_thread() are waiting for a write to
pipe to complete, while both pipes are filled with 57 entries each.
Since SIGIO is blocked at that time, ubd_intr() isn't started,
and the system hangs.
I think, we have to add some "flowcontrol", but have no idea how
to do this.
I don't know, if this could be problem on 2.6 host also.
