loggingTestingMutex

A mutex to synchronize tests that affect the core logging state. You can either synchronize on this object, or call acquireLoggingTestingLock() to ensure that only your test has access to the logging state. Be sure that if you acquire a testing lock, that you release it afterwards with releaseLoggingTestingLock().
