+5  Q: 

Ruby multithreading / multiprocessing readings.

Can anyone recommend any good multithreading / processing books / sites which go into detail about the intricacies of Ruby multithreading / multiprocessing?

I tried using ruby threading and basically in deadlock-free code on 1.9vm it ran into deadlocks in jruby. Yes I realize the differences are drastic (jruby has no GIL) but I wanted to know if there are strategies or set of classes for multithreaded programming in ruby that I just need to read up on.

Side note: was kinda weird going from java to ruby having to define if i want a re-enterent lock vs not.

+1  A: 

If you use Ruby 1.9 you can try Fiber it's a big improvement in threading in Ruby

I wouldn't call it an improvement, just a different feature used to accomplish similar tasks. A big improvement is threading in JRuby's implementation.
