thats far beyond my dexterity.

When one follows ..
http://docs.python.org/inst/tweak-flags.html#SECTION000622000000000000000 
http://www.zope.org/Members/als/tips/win32_mingw_modules

..this seems only to cover the immediate python dll issues. What happens with the C runtime libraries? You'll bind 2 different C-RTLs (DLLs) etc.? 
And what happens for example with heap objects created with one C-RTL and deleted/free'd with the other?
