Perl 5.8.2, Threads, and mod_perl-1.99_10

Hey Everyone, got a fun question.  I recently upgraded to perl 5.8.1, 
mod_perl mod_perl-1.99_10, and apache 2.0.48.  What can I say, I want 
the best of the best.  Anyway, all went well, except now I lack the 
ability to spawn a thread while under mod_perl.  I can spawn threads all 
day long under normal perl, but any creation of a thread under mod_perl 
just results in a segfault of the apache process (the segfault (11) 
shows up in my httpd log).  I'm kind of at a loss where to go from 
here.  I don't have any handy dandy error messages to go from.  This all 
worked prior to the upgrade.   I realize that I don't have a dump or 
anything to really show, but I don't exactly know how to get that from 
inside mod_perl. 

Thanks for any suggestions.
