At this point, I'm leaning towards setting the upper bits of the TID for all 
MADs that are not responses.  (This is for usermode only, so kernel agents such 
as the CM are left as is.)

I think that a response can be identified as:

Response bit set || trap repress ||
(class=BM && attribute modifier response bit set)

The last check is missing from current code, and the SEND checks listed above 
seem unnecessary.
