The bad:
OpenIB frequently crashes with the error:
***************

135:mca_btl_openib_endpoint_post_send] error posting send request
errno says Operation now in progress[0,1,2d

Hey Troy,
I made a very small change in the trunk, here is a patch.
I was unable to test this so if you could test this and report back
the results that would be great, also, instructions on reproducing
this would be great.
Thanks,
Galen
