MySQL mutex implementation.
There are three "layers": 1) native_mutex_*() Functions that map directly down to OS primitives. Windows - CriticalSection Other OSes - pthread 2) my_mutex_*() Functions that implement SAFE_MUTEX (default for debug), Otherwise native_mutex_*() is used. 3) mysql_mutex_*() Functions that include Performance Schema instrumentation. See include/mysql/psi/mysql_thread.h
