Hello Galen,
Finally I've got some time to look through the new code.
I have couple of notes. In pml_ob1_rdma.c you try to merge
registrations in the number of places. The code looks like this:
btl_mpool->mpool_deregister(btl_mpool, reg);
btl_mpool->mpool_register(btl_mpool,
new_base,
new_len,
MCA_MPOOL_FLAGS_CACHE,
®);
How do you know reg is not in use? You can't deregister it if
somebody
is using the registration!
Good catch... this should check the reference count and
only deregister when the reference count actually goes to zero...

Yes, this was a good catch.. This was causing all sorts of fun for us!
Thanks,
