As I told Mark earlier, I finally found the bug in his code.  It was
truly a work of art; it took me over 3 weeks to find and ultimately a
marathon debugging session using edebug32, fsdb, and gdb.

BTW, the fix has been tested and works on my machine; others are welcome
to try it but it should work fine now.  Well, words can't adequately
describe it; see for yourself.  ;)
