New Revision: 61970
URL: http://svn.boost.org/trac/boost/changeset/61970

Log:
Serialize running of MPI tests to minimize overloading systems.

Several in house complaints necessitated solution to running
parallel Boost tests and MPI tests.  Best short term option seems
to be to serialize MPI tests using Boost.Build jam semaphore
capability.
