bq. I had originally thought of calling it MessageSelector... - see
below for my thoughts on the purpose of this class vs Messages class, and why
I've separated the two.

bq. I didn't like MessageSelector because I felt it was likely to be
confused with a selector i.e. filter as specified by a consumer. It is the
component that determines which subscribers are 'allocated' particular
messages, hence the current name.
bq.
bq. How about MessageDistributor?
Aside from the outstanding naming issue - is this patch something we want/good
enough for inclusion on trunk for 0.14? We're getting near the close-down
date for including large changes on trunk, and I'd consider this patch a large
change.
As far as the MessageAllocator re-naming: I'm a bit too used to the existing
names to make a good judgment call here. So I did a lookup of Allocate in my
thesaurus and "Distribute" came up in the top ten. I'll go with
MessageDistributor unless I hear otherwise. And to muddy the waters further,
here are a few more matches from the thesaurus for your consideration....
admeasure, allot, apportion, appropriate, budget, cut, designate, dish
out, divvy, earmark, give, grant, mete, set aside, share, slice, appoint,
assign, budget, cut, cut the pie, distribute, divvy, dole, shell out, split up
:)

bq. Summary
bq. -------
bq.
bq. This implements QPID-3346. I'd like to get this onto trunk.
bq.
bq. This patch does not include optimizations I have made - I'll be reviewing
& submitting these separately as they involve more intrusive changes to the
Queue API. Ignore for now the TODO comments in the MessageGroups source files.
bq.
bq. Performance testing suggests that this patch has negligible effect on
legacy traffic performance (non-grouped traffic):
