  I know the old litany of not moving memory from a completion routine.  What
I'm wondering is if it's safe to make an asynchronous _Control call from a
completion routine.  I was thinking about the AppleTalk drivers specifically;
if I have all the response and request buffers allocated beforehand, is it
safe to send an async SendResponse in the completion routine of a GetRequest?
Thanks for any thoughts on this subject.
