Overview

ThreadSafe is a delegate wrapper class used for implementing gross thread safety around existing objects. when an object is wrapped with this class as

ts = ThreadSafe.new{ AnyObject.new }

then ts can be used exactly as the normal object would have been, only all calls are now thread safe. this is the mechanism behind the ‘threadsafe’/:threadsafe keyword to Slave#initialize
