Heh, I'm not quite following what you mean.  Can you please elaborate?
Also, on the second thought, it probably would be better to flush
async calls before unbind.  It's fragile to require indivdiual drivers
to do that and I can't think of benefits of doing so.  It's not like
the unbind / unload paths are hot in any way.

Thanks.
