Log Message:
convection.py checkpointing uses mkdir/rmdir, and under MPI there
was a race condition.

mkdir needs to be run on only one CPU and then a barrier to prevent
working processors from using the directory before it exists.

Added methods domain.MPIBarrier and domain.onMasterProcessor() to
implement this technique.

A more general solution might be possible in the future.
