application -- need ctrl-c handler for apps

[Fred T. Hamster]

1. ctrl c handler must cleanup
   1. the control-c handler that we will activate when break is hit needs to clean up the program objects like the shared memory chunks.
   2. can it invoke the prog wide cleanup and then just exit?
   3. that will not shut down all objects cleanly however, including threads.

really need ctrl c handling!

so we can set an exit function or something that
leaves the script right away and sets return value
to failure code.

otherwise, you hit ctrl-c and the current subshell quits
and the script just tries to keep running.

this needs to be a really tiny little bit of code
we can load easily into any bash perl python etc script.

hmmm, this is both for scripts and for our apps!
