Right -- and it should be easy to find more offenders by having an
assert statement soak in the builds for a while (or by default in
Was if it was ever part of the (or a) design to allow re-entrant
calls to progress from the same calling thread ? It can be done but
callers have to have a holistic view of how other components require
and make the progress happen -- this isn't compatible with the Open
MPI model of independent dynamically loadable components.
