Dave, thanks for taking care of this. I've put the configure tests (detect ch3:sock using MPIDI_CH3I_sock_set and the fix with MPIDI_CH3I_sock_fixed_nbc_progress) into PETSc and all is well using the Issend/Ibarrier algorithm by default for all bug-free configurations.

I think checking of the "MPIDI_CH3I_sock_errno_to_mpi_errno" symbol should be unique enough to detect ch3:sock.

Thanks, I'll add this test and combine it with a version check (unless there's something better) once the bug is fixed.

I can add a special "MPIDI_CH3I_sock_with_fixed_nbc_progress" symbol (or whatever) for you as soon as it's fixed.
