Great.  There are, I think, 2 holes that would need to
be filled - so it may be something we'd like to postpone
doing.

Hole 1:  The QM doesn't know about orphaned SM_UNSUBMITTED
queries. This shouldn't happen but can if the QO destructor
is not called due to a usercode crash or due to mishandling
the CORBA reference count. One way out of this is for
the QO to request the list from the QE and the QE requests 
the executing list from the QM & concats this to an 
unsubmitted list within the QE that is then returned to
the QO. (whew)

Hole 2:  The QE cannot abort a query that it has flushed
from its memory.  For these cases, we could allow the
QE pass the "abort(token)" onto the QM when the QE doesn't
doesn't recognize the token.

In any event, I'll put together a struct that we'd like
to have and we can discuss such details as time allows.
Maybe we should take up this admin item in a more general
administration discussion at the April meeting.

Thanks, Jeff
