I think this is a serious problem (and thanks, amaury, for finding the spot). comtypes, like ctypes, uses quite a bit of isinstance calls. It is the reason that the comtypes unit tests run between 8% and 25% slower with trunk than with python 2.5.1. If I comment out the code that you mentioned, python trunk is slightly faster than 2.5.1. I suggest to raise the severity.
