/**
 * Replaces the ProxyClassFinder in the ClassLoader with the real ClassLoader.
 *
 * xautoload has a number of cached class loaders, working with APC cache or
 * other key-value stores.
 *
 * The cached class loaders use the decorator pattern, and decorate a
 * ClassFinder object, that will only be consulted on a cache miss.
 *
 * xautoload will first give the ClassLoader a ProxyClassFinder that wraps the
 * real class loader. On the first cache miss, this ProxyClassFinder will
 * notify all subscribed CacheMissObserverInterface object.
 *
 * The job of this particular observer is to replace the ProxyClassFinder, once
 * it has done its job. Instead, the ClassLoader will get a reference ot the
 * real ClassLoader, saving the overhead of going through ProxyClassFinder each
 * time.
