Subject: Re: [OMPI devel] matching code rewrite in OB1
From: Richard Graham (rlgraham_at_[hidden])

Gleb,
  I would suggest that before this is checked in this be tested on a system
that has N-way network parallelism, where N is as large as you can find.
This is a key bit of code for MPI correctness, and out-of-order operations
will break it, so you want to maximize the chance for such operations.
