Yes, I have already said I'll post a test case. :)

The krping tool will be the culprit.  Its the kernel equivalent of rping 
and has been around for a long time in one form or another.

It is available at git://git.openfabrics.org/~swise/krping

It currently supports dma mrs and regular mrs only.  I'm adding fastreg 
support now.  And I want to add mw too.
