I've been going over the previous posts. Are these attempts to replace
the RVM patch? I don't mean to rain on anyone's parade, but I'm already
using this exact method to run multiple embedded Perl VM's. And I hate
it. It's a hack, and it kills me to have to use it. In fact, I'm hoping
to use Lua's coroutine support specifically because juggling multiple C
stacks is ugly and very limiting. I then have to worry about which stack
particular functions get called on... which I don't like. I would much
prefer to maintain a single C stack.

That's my $.02.
