/* OS/2 PM main program - creates a hidden window, and starts Python
* interpreter in a separate thread, so that Python scripts can be
* run in PM process space without a console Window. The interpreter
* is incorporated by linking in the Python DLL.
*
* As it stands, I don't think this is adequate for supporting Python
* GUI modules, as the Python thread doesn't have its own message
* queue - which is required of threads that want to create/use
* PM windows.
*
* This code owes a lot to "OS/2 Presentation Manager Programming", by
* Charles Petzold.
