Subject: [ruby-core:33825] PATCH: REE fast-thread.patch: stack_free() not called in rb_thread_die().

http://code.google.com/p/rubyenterpriseedition/issues/detail?id=57

Helps reduce memory usage for short-lived Threads that might not be GC 
fast enough.

Might be relevant to other MRI builds with the fast-thread.patch.

Cheers,
Kurt Stephens
