Tee hee hee. How do I initialize the mutex that protects the mutex? I think it's time to learn from the POSIX threads mutex implementation, wherein it is impossible to statically initialize a mutex, and to obtain that appearance, you have to trick the loader into doing the work using the section which is used for the construction of virtual base classes in C++ (see my modifications to the STL, as applied to the Moscow Center for Supercomuting Activites STL, which is the most up to date STL available).
