Hello, Monks:
I have been stuck by this problem for a few days. I have a somehow complicated regular expression inside a child thread in a multi-threaded program. 
my ($mail)=$string=~m/([\w._+-]+@(?:[\w-]+\.)+\w{2,5})(?<!\.jsp|\.asp|
+\.jpg|\.htm)\W/mi;

When the text to be matched($string) is a little over 1 Megabytes, this regexpression runs forever and never return.
But when I run a single-threaded version of the same program, it works perfectly fine(The regex returns instantly). I am wondering whether there are some settings or limits imposed on the child thread of a multi-threaded program. Could anyone here enlight me on that?
I am running ActiveState Perl 5.10.0 on Windows Platform. Thanks in advance.
