/// This is a special primitive that anybody can lock at any point, and should be done so before locking global primitives.
///
/// Intended use case: AU_LOCK_GLOBAL_GUARD(gMyGLobalResourceMutex) or AU_LOCK_GLOBAL_GUARD(gSingleton.mutex)
///
/// I'll let you in on a little secret: it's not special; it's just the read side of a read write lock, with some special invokation logic on the write side.
/// One should always expect this to *read lock* to pass without blocking.
/// Once a thread is demanding the forceful termination of another, the write side is acquired, and future * non-recursive read * acquisitions are rejected until the requested thread has terminated.
/// As previously stated, this is intended for protecting the lock guard of global primitives. Why? Global primitives cannot be as easily recycled.
/// You can always trash a memory heap / component db / etc and reset. The forceful shutting down of a subsystem is viable, especially if their heaps are isolated and their IO resources tracked under a watchdog.
/// On the otherhand, it's quite difficult to wrangle force thread shutdown, for two and a half reasons:
/// 1) POSIX APIs do not allow force terminate,
/// 1.5) clang is broken - it doesnt allow us to catch ghetto gcc abi::__forced_unwind - not that other users cant clobber these to begin with, and
/// 2) global locks may never be released.
/// 1. Isn't an issue for us.
/// 2. For short global read or write operations, GetShutdownLock can be held to ensure force thread termination doesn't mess up future consumers of a global resource.
