+/** The Mutex class represents a mutex, which can be used to keep threads
+ * properly synchronised. Use mutexes sparingly, as they are a good source
+ * of thread deadlocks etc, and should be avoided except where absolutely
+ * neccessary. Note that the internal behaviour of the mutex varies from OS
+ * to OS depending on the thread engine, for example in windows a Mutex
+ * in InspIRCd uses critical sections, as they are faster and simpler to
+ * manage.
