Detailed Description

An object oriented wrapper around a non recursive mutex.

A mutex can only be unlock()'ed, by the thread which lock()'ed it. A trylock is a non blocking lock action which fails or succeeds.

Warning:
Mutex instances should only be created in soft realtime, since the initialisation of a mutex can not be done in hard realtime.
