now since tcpmp is written in unmanaged code and it behaves as i have described... need i say more?

You seem to know more about the specifics than I do ... But I have MSVC 2008 and at least one small app I coded myself works with the renaming method (and a few others that I didn't)...
The app is a simple carpenter's calculator with algebraic formula parsing and common construction formula templates ... Before I added support for multiple memory slots in the calculator I used to run multiple instances of the same process when I had two things at work to keep track of at the same time...
It is unmanaged code (C++ WIN32 API + WM5 SDK) and I never did anything to it to prevent the type of checking you are talking about (obviously, since I wasn't aware of the default behavior until you mentioned it) so ... While I acknowledge that you seem to know more about the specifics than I do ... Apparently there is an exception to the rule...
In any event, I would be curious about the lines of code you mentioned but I don't want to take any more attention from the OP's original question so I'll leave off here... You could PM them to me if you are bored sometime
