I hope everything in Ruby (including 3rd-party extensions/gems) can be
made fork-safe by default (if they run on a system with fork) one day.
I don't agree with blindly mimicking OpenSSL upstream behavior if Ruby
can be made easier-to-use.

Yes, I confirmed OpenSSL can't change the current behavior:
http://marc.info/?l=openssl-dev&m=130298304903422&w=2

I'm still hoping to get a list of things that need to be reinitialized
in OpenSSL after fork() from openssl-dev...

I would be 100% in favor of making something analogous to
pthread_atfork() available in Ruby.  It would make it much easier to
manage various resources in a multi-process situation

No comment on the appropriateness of pthread_atfork() inside an ext.
