It depends on what you want to achive with the GMutex. If no two
instances of classes derived from your base class may be accessed at the
same time, you have to have one GMutex for all of them, i.e. a static
member. If only every individual instance has to be protected, make
GMutex a normal member of the base.

Bye,
Sebastian
