Description:
------------
In order to effectively recover shared memory after an Apache process crash, it would be useful to attach to the shared memory segment and then be able to tell whether or not you are the only process that is currently attached. This way you will be able to check some value in shared mem and tell whether or not that value is lying around due to a program crash.

This functionality could also be useful to implement reference counting for the shared mem. The last process to detach from the mem segment can remove it.
