I'm not ignoring that failure, but I don't think it is a showstopper. If 
it's broken with Intel 10 on Linux, I think that's something we can live 
with for 1.40 and fix for 1.41. I'm satisfied knowing that MPI is not 
fundamentally broken across the board.

The failure you mention certainly bears investigation, though. Could you 
open a bug report against MPI? If it turns out to be a MPL issue, we can 
reassign it.

Thanks,
