- *  DESCRIPTION
- *      Lock the global mutex. The global mutex is a single pre-initialised

- *      to use. The limitation is that there is only one single lock shared
- *      between all code. Consequently, it must only be used very briefly to
- *      either protect simple one-time initialisation or to protect the creation
- *      of a dedicated mutex by calling CsrMutexCreate.
