Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010
  Processing by HomeController#index as HTML

Synchronizing a Pool of Resources

Here are several approaches for synchronization around a pool of limited resources that are checked in and out by a gang of threads.

Pools

There are three different pools: MonitorPool which uses monitor.rb, MutexCondvarPool which uses a Mutex and a ConditionVariable, and SemaphorePool which uses a java.util.concurrent.Semaphore (only under JRuby).
