Ok, I totally blew it on this one. The problem is that you are launching too many children without reaping any of them; a scenario which reduces to this:
perl -le "print $p, ':', ++$i while $p = fork"
The solution under unix would be to hook $SIG{CHLD} and reap them properly, a la
perlipc. Unfortunately signals don't work properly under windows, so I'm not sure how you should handle this. Perhaps hack something up which involves
waitpid -1, &WNOHANG; when the number of simultaneous children get high. You may also want to consider running under Cygwin.
