Weightless threads?

ruby-talk

I was reading through IBM Developer Works newsletter today, and I came
agains something very interesting: weightless threads. This is mentioned
in the Python column. They say that they incur virtually no overhead,
and that one could run a large number of them even on a mediocre
machine. I was wondering, has anybody had any experience with those? If
so, when we will see such things in Ruby?

Sure; Squeak (Smalltalk) has very lightweight threads. People have had
upwards of 10000 threads with no problems.

It’s a very simple architecture: there is a queue of ready-to-run
processes at each priority level. And Semaphores keep lists of
waiting processes, as well.

There is just enough VM support to do the actual process switch.
