I ran the attached program, commenting out first one 'while' loop and
then the other, on both Darwin and Linux, with Perl 5.14. In all cases,
the program simply hung; none of the 'print' statements ever materialized.
So either I misunderstood what I was supposed to be doing, or the
program still does not work. Should it have?
Thank you very much.
