Vish --
In general, this sounds like a great idea.
We talked about this on the call today, and it looks like it's going to take a
bit of thought into how to integrate this into OMPI. I.e., we might have to
adjust the mpool and/or allocator frameworks a bit first.
Is there any chance that you can attend the OMPI face-to-face dev meeting in
late January?
