I get different results in Perl.  For example if I do two threads, each with
a loop printing out the numbers 1-100 (or even 1,000) in Perl, the output
is interspersed.  Thread 1 prints one or more, Thread 2 prints one or more
and so on.  If I do it in C++, Thread 1 prints them all, then Thread 2
prints them all.

That's what I mean by it being different at this level.  The Perl
interpreter is handling switching between the different Perl threads.
