Subject: Re: Ruby embed called from a pthread

Wow Peter, what a pretty hack :-) It really works! Thanks again.
Shouldn't ruby provide something like this? (but not hacky)

After a long period of developing, I finally soved all my ruby
problems. As a shared library, I receive call from many threads. So,
when the first thread needs ruby, I spaws a new pthread dedicated to
ruby and initialize all its stuff. I created some wrapper for each of
my C methods. When my method is called, I write its arguments to a
global variable, asks my ruby pthread (not a ruby thread) to run it
and it wakes me when it is done. All ruby calls uses the Peter's Hack.

Again, maybe ruby could already provide something similar to my solution.

Anyway, it now works!
