My preference for handling this is to detect and discard duplicate requests, and 
verify that response MADs match a request when being sent.  See the mail thread 
starting at:

http://openib.org/pipermail/openib-general/2006-April/020703.html

This will also help us add in support for DS RMPP.

For kernel clients, I anticipate that this sort of change is fairly small. 
Userspace support requires a bit more work, especially if we don't want to 
change the ABI.
