What happens to a mutex in shared memory if all the processes using that memory go away? Does that shared memory stay around, or would the mutex have to be reinitialized if one of the programs using it gets restarted? Is there any way to test to see if a mutex has been initialized? -- These are my opinions, not necessarily my employer's.
