------

Agenda:
1.	Questions raised on the list

1.1	(Jeff Messing)
	Memory Deregister call flags - what about out-of-range values?
	Do we want a default operation, with modifier flags?

	a) Implementations should error-check the arguments.
	b) No concensus for which op should be default.  Leave as per
		API v0.5 specification.

1.2	(Vish)
	exs_qstatus: Should this be analogous to exs_qmodify?

	[I didn't record the points raised un discussion, sorry]
	Concensus was yes, probably.

	AI: Vish to publish new function prototype & semantic on the list,
	for later approval.

1.3	(Jeff)
	Wasn't the async verison of sendfile/recvfile to be folded back
	into send/recvmsg?

	Concensus: No, not enough support.

1.4	(Jeff)
	exs_qhandle_t is typdef'd as an int.  Why isn't this a
	void * similar to the exs_mhandle_t?

	Concensus: Accept; a void * permits implementations where the
	queue handle is a pointer while still supporting those where
	it is a file-descriptor (integer).  The current does not.

	AI: Louis to up-rev the API.

1.5	(Louis)
	shouldn't qdelete only fail if there are still async ops in flight
	and not if there are still event registered?  Why force the user
	to deregister all events if that can be done in qdelete?

	No concensus.  Issues:
	- May cost implementation to track inflight async ops, rather
	  than registrations
	- Some hardware may make it difficult to cancel/retrieve inflight
	  ops.

	AI: (Everybody!) continue discussion on the list.

	Recommendation: Implementations should document their behaviour
		on async-op cancels; whether a cancel always succeeds,
		may fail (in what situations), always fails.

At this point we ran out of time.  There are still outstanding queries
from Louis, at the top of his API v0.5 posting.  Discussion to continue
on the list and at the next concall.
