* NAME

* DESCRIPTION
* Lock the global mutex. The global mutex is a single pre-initialised
* shared mutex, spinlock or similar that does not need to be created prior
* 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.
