- bcast now works properly for root!=0 and multi-fragment messages
- destroy mpool when communicator is destroyed
Still need to implement:
- "in use" flags for groups of fragments so that "wrapping around" in
the data segment doesn't overwrite not-yet-read data
- ensure that shared memory isn't removed before all processes have
finished with it (e.g., during COMM_FREE)
