/**

 * Adapter class that serializes all Log() calls on the underlying logger into the same thread.

 * That is, a call to Log() from a thread that did not create this AO will block until the AO has

 * completed the log in the AS thread.

 * 

 * This class is provided to allow the use of loggers that would otherwise KERN-EXEC 0 panic if

 * used by multiple threads.
