[python-win32] Technique to limit number of instances of our application under Terminal Server

[python at bdurham.com]

Hi Link,

> If the limit is one, then a lazy and dirty way is to bind to a tcp 
port (just pick a fixed one that's not used by other services - you 
could make it configurable), and exit if the bind fails.

An excellent idea. I'm leaning towards either this idea or a
collection of mutexes.

Thanks for your feedback,
