As for dbus-0.93, the mutex functions return value has been removed and inside
the lock and unlock function, there isn't any assert to check the return
value of the underlying mutex function. This is definitely a mistake to
remove chance to chase hard to find bug.
What's happens in the following case:
* the mutex is not valid one
* the mutex is already locked although it's a non recursive mutex.
* the mutex is unlock although it's not locked
Checking return value for system function such as the mutex one is not an
option, it's necessary to produce high quality software.
