- Move the "process 0" logic out of the main loop in reduce to make
the code a bit less complex (at the price of slight code
duplication, but it iss now significantly easier to read)
- Fix problem with uniquenes guarantee in the bootstrap mpool -- using
the CID alone was not sufficient enough to guarantee uniquenes; now
use (CID, rank 0 process name) tuple to check for uniqueness
- Made a few debugging help changes in coll_sm.h; especially helps
debugging on uniprocessors
