The mutex, associated memory, the entire owner's process and all other 
processes that might have access to that mutex (and associated data in 
memory) are considered to become "toasted". In POSIX, a thread thread 
can't terminate "abnormally" not causing process termination; so the 
entire owner process is basically gone. The rest (killing all victims, 
cleanups/rollbacks and takeovers) is usually handled by some fully 
isolated "recovery system".
