I followed the thread (I think) -- I was hoping we'd get some good time
in Singapore to discuss this - will you (and Rick+ Stan) be there?

I'm torn, the lid approach means a lot of added messaging to essentially
provide queue index semantics - but I also like the generic concepts of
LIDS (although I personally think LID length should be fixed per
session, not per spec.)

Given that lids are so immature, I don't think we should hold up pause.
Let's get it done and out there, and *if* we come up with something
better in a year or two we can deprecate pause.
