 Are your feelings strong enough to commit bin/38676 so that people can use
 pw(8) safely and concurrently on mondo huge master.passwd files?  :)
 
 bin/23501 was supposed to have fixed the problem, but it doesn't appear to
 have been committed before it was closed.  bin/38676 is a revised/improved
 version of the original patch in bin/23501.
