 *

 *  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.
