This documentation:
http://www.mcs.anl.gov/research/projects/mpi/www/www3/MPI_Comm_create.html
states that MPI_Comm_create is not interrupt safe.
Note that I am not a computer scientist. What would be a scenario where interrupt safety might be a concern? Could oversubscribing cores with MPI tasks cause
problems?
