Worker/thread pools in Rake

I've spent a little bit of time trying to get thread pools into Rake.



This article explains the basic Rake "multitask" method to ask Rake to parallelize a number of processes.  But it's not ideal.



Rake will start a new thread for each parallel task.  This is not very sensible.  Normally one would run make with -j2 or -j4 etc.  Not -j100.



So I've taken the thread pool code from and then replaced the multiuser method in Rake.  Easy.



I'll put the code up here in a moment.
