* New/improved bootstrapping technique for DLLs * First cut of the MPI handle debugging interface. It is still evolving, but the interface is getting more stable. * Some minor bugs were fixed in the unity topo component (brought to light because of the new MPI handle debugging stuff). Fixes trac:1209. This commit was SVN r17730. The following Trac tickets were found above: Ticket 1209 --> https://svn.open-mpi.org/trac/ompi/ticket/1209
