In a given comms session, the barrier module maintains a hash of active barriers by name. A barrier name is retired after use, but as there is no mechanism to tell one barrier from another beyond the name, it is best to play it safe and make them unique.
Unique barrier names could be generated by combining the $FLUX_LWJ_ID
(or $SLURM_STEPID
) and a per flux_t handle sequence number. This hueristic could be activated when flux_barrier is called wtih a NULL barrier name.
