for two separate runs we can use slot_list parameter (
opal_paffinity_base_slot_list ) to have paffinity

Lenny's point is true - except for the danger of setting that mca

I ran few tests and the only combination leading to a deadlock is
openib and self. As openib is the only BTL supporting self
communications (except self of course), I guess it interfere with self
in some more or less strange ways. I didn't had the time to dig deeper
yet to see what exactly
Ok. FWIW, Pasha and I think that openib has supported "send-to-self"
for a while (we don't know exactly when; but Pasha thinks it is very
old code that we don't check for self in add_procs). But it only
broke recently.
