ISTR solaris uses a different driver entry point for aio and does not
biowait(). Instead, there is a kernel aio structure/process to keep
track of pending I/Os, and waiting is done on that structure only
when the process specifically desires to wait for I/O completion.
However, it has been quite a while since I was messing around with
that code, so my memory may not be all that accurate.
