Yup, that makes sense.  (Duh!  Shoulda noted that one!)  Hmm, maybe I'm
barking up the wrong tree.  Somehwere the PWS is losing file handles, but
maybe it has nothing to do with threads.

Thanks, Lex and Andreas, for your hunting!  I'll go back to trying to
figure out some way of replicating the bug reliably -- or getting rid of it
:-)
