Description:
Threaded each
An addition to the Enumerable Ruby module that allows easy use of threaded each and each-like iterators. It's a very simple producer-consumer model. . If you're using stock (MRI) ruby -- you probably shouldn't bother with threach unless you're doing IO-intensive stuff. It'll just slow things down. But if you're using a ruby implementation that has real threads, like JRuby, this will give you relatively painless multi-threading.
