Inheritance diagram for MutexLockBase:
Detailed Description
The main purpose of this base class is actually to allow setting of usleep_granularity across all locks.It would be nice if we just put functions in here so we could reference locks without regard to the number of doors, but then all processes which use the lock would have to have been created via fork to handle virtual calls properly, and I don't want to put that overhead on the otherwise lightweight SoundPlay process under Aperios.
