Why not use a static area of the shared memory segment? Is it possible
to have a spinlock over it so that an external utility can take a snapshot
of it with the spinlock held?
Also, this could work for other stuff as well, instead of overloading
a lot of signal handlers one could just periodically poll a region of
the shared segment.
just some ideas..
