=begin
mixing threads and forks results in double free crashes. Unfortunately I haven't been able to duplicate with less than 500K lines of code.

The original allocation happens here :
rb_thread_start_0
blk_copy_prev
frame_dup

I've attached a patch which fixes the problem for me, but I'm not familiar enough with
the undocumented ruby internals to be sure that it won't create a memory leak by not freeing
some things that should be. This patch needs expert review before accepting.

Thanks,
Barry
