[python-win32] WIN32COM: Cannot get event interface given a wrapped dispatch pointer

> It is my opinion that the architecture is flawed,

While you have obviously struck a bug, I need to understand it more before I
can comment further.  I'll try and reproduce it using the C++ test object
and IDL file - if you could help do that it would be greatly appreciated and
help a timely solution.

This is the crux of the problem and shouldn't be happening.  However, the
gencache mechanism does allow for cross-module definitions - so there
shouldn't be a problem if we ensure that each interface only appears exactly
once in the gencache.

Why do you say that?  If the typeinfo references an IID or CLSID, why can't
we trust it?  In what scenario would it be incorrect?  It seems to be
working well so far, not withstanding the bug which you say causes duplicate
entries for the same interface.
