function that may no longer exist or is being deprecated. There's lots of
work going on to remove some locking stuff, and that may have been one of

Lots of suggestions on the net seem to suggest replacing all instances of
init_MUTEX with sema_init (use a semaphore lock instead of a mutex lock).
Might be worth a try :)
