/**
 * Test log queue that allows verification of calls to <code>log</code> and <code>flush</code>.
 * <p> 
 * Actually this class does not support any of the special features of DispatchingLogQueue.
 * It will not even forward the log record to it.
 * It only extends DispatchingLogQueue because AcsLoggingHandler requires a DispatchingLogQueue in the ctor
 * and I see no big advantage in refactoring this.
