[python-win32] Memory Consumption when running Python COM Script

I've set a breakpoint on PyParser_ParseStringFlagsFilename. It gets
called for every iteration of the loop, with the same arguments. For
each call, the process memory usage grows by 4-5 K.

PyTokenizer_FromString
PyParse_ParseStringFlagsFileName
Py_CompileStringFlags
builtin_compile
PyCFunction_Call
PyEval_EvalFrame
PyEval_EvalCodeEx

The arguments for PyParse_ParseStringFlagsFileName are:

s = "def AttValue(self, Attribut=pythoncom.Missing):..return
self._ApplyTypes_(1, 2, (12, 0),((9, 1),), 'AttValue', None,
Attribut....)."
filename = "<COMObject <unknown>>"

This appears to come from line 300 in dynamic.py.

I mean a self hosted script, running through an inproc ActiveScript
python engine.

This is related to the other question I have with AddTypeLib. The
function doesn't seem to generate any python Code for the actual
methods. I would like to use the complete typelib information (with
method code) in a python script.

I am not really sure how to debug the python com code. I have tried
enabling the debug output in dynamic.py, but I am only getting
incomplete information.
