Yeah, this causes me to hold my tongue on a regular basis ;-)

I think Gil must have missed my email a while ago showing slides that
prove InfiniPath's cpu overhead is lower than Mellanox for smallish
MPI messages. It's well known that offload is often bad for small
messages; InfiniBand is not an exception to this rule.
