--- Comment #6 from Henrik Karlsson  ---
I would write code that can traverse through all dlls in system32 and make sure
that works.

Then try to write some custom dlls that covers the various cases. I have no
idea which parts of the dlls that trigger what behavior though.. When I was
messing around with this it really felt very arbitrary, so I think this would
be quite hard.

Even though it would be great to have full unit test coverage I think it is
more important to just make it work with the dlls in system32 folder once. It
is a tricky domain to make unit tests without copying binary data from windows.
