I think your on the right lines.  When you lock a mutex, you are 
preventing any other thread from acquiring a lock on the same mutex 
until the thread that has locked it successfully, releases that lock.

The thread attempting to lock an already locked mutex will block until 
the mutex is unlocked.  Unless you use another type of mutex (e.g. 
try_mutex or timed_mutex)
