Which kind of "regular mutex" (there are so many flavors now)?  Under whose
pthreads implementation?  Etc.  There aren't easy answers here.  Note that
current CVS Python uses POSIX semphores instead (when they're available),
which raises a whole 'nother set of issues.

AFAICT, you're all still trying to figure out whether there's "a problem"
here to *be* solved <wink>.
