Interesting...if I add use threads::shared; to the MyFrame package I see the following: 
Thread 1 terminated abnormally: Can't locate object method "blessed" v
+ia package
 "Can't locate object method "update" via package "Class::MOP::Class::
+__ANON__::
SERIAL::2" at thread_test.pl line 115.
" (perhaps you forgot to load "Can't locate object method "update" via
+ package "
Class::MOP::Class::__ANON__::SERIAL::2" at thread_test.pl line 115.
"?) at thread_test.pl line 118.

I'm at a complete loss
