Single Application Instance Example

[Chris Lambacher]

Does anyone know of an example of how to make a Python program only
run a single instance.  I am specifically looking for examples for
win32.

I think I should be able to do this with win32all but the method is
not obvious.  Preferably I would like to be able to get a handle to
the already running instance so that I can push it to the foreground
as well.

Thanks
-Chris
