I thought the same thing!  Paul Boddie introduced me to POSH some
months ago.  I don't recall the implementation of synchro. objects in
POSH, but IIRC, 'multiprocessing' uses native OS handles opening in
multiple processes.  It could be that there would be substantial
overlap, or the trade-offs could be significant.  For one, the above
combination only permits strings to be shared, not objects.
