Hi there!

Does Ruby threading model uses a global lock as Python uses?

Thanks!

No. It's worse (in a sense). It uses its own green thread.

Thanks for your answer, Matz! Can you give me a tip where I can learn
more things about this matter? I mean, some URL for
documentation/article or where to look on the Ruby source code?

Thanks again!

See http://www.ruby-lang.org/en/... for source download
instruction. For threading matters, eval.c has everything.
Note: beware. it's a black magic inside.

Jumping directly to eval.c can be very scary.
It is probably easier to follow order given in

I download and compile the sources on every release, I made a Slackware
build file some months ago for it. :-)

I opened eval.c before, just needed to make sure I was on the right
place (I searched for "thread" on the source code and there I was) and
as you and Tomasz said, it's scary and looks like black magic going
directly there, but I'll take a look carefully.

Thanks again!
