Assume that the vulnerable service is a third-party binary, and the administrator cannot change it. Also assume that users must be able to access other named pipes on this system besides the vulnerable one.

Divide Windows Pageant into two threads. The main thread runs both the visible GUI and the named-pipe listener, and has a main event loop that selects between its Windows message queue and a set of event objects from winhandl.c , more or less exactly like PuTTY's event loop. The secondary thread creates the invisible window that WM_COPYDATA ...
This is done in the style of a single class, that should work like any other io-based object in Python. Help is much appreciated with anything regarding performance, documentation, or anything else.
