Pardon my ignorance, but what does BKM stand for?
Open MPI does not currently implement a timeout-capable MPI_WAIT. Such functionality probably could be implemented (e.g., in the MPIX "experimental" namespace), especially since Open MPI polls for progress -- it could check a timer every so often while polling -- but no one has done so.
