## THREAD AND INTERRUPT SAFETY

This routine is thread-safe.  This means that this routine may be safely used by multiple threads without the need for any user-provided thread locks.  However, the routine is not interrupt safe.  Typically, this is due to the use of memory allocation routines such as  *malloc* or other non-MPICH runtime routines that are themselves not interrupt-safe.
