// Port of pflib/external/openal/CAMutex.h (Apple Core Audio utility class, Playground SDK 4.0): CAMutex, a pthread
// mutex that remembers its owning thread, so Lock / Try on the owning thread return without touching the pthread
// mutex. CAMutex.cpp is ported next to this file. Layout from the DWARF of parity-out/sdk/dbgobj/CAMutex.o
// (size 56): +0x00 vtable, +0x04 mName, +0x08 mOwner, +0x0c mMutex.
//
// The SDK header's nested Locker helper class is not carried (no ported code uses it). Callers lock with
// `bool wasLocked = guard.Lock();` and unlock only when that returned true (DWARF local "wasLocked").
