Summary: PyCom_PyObjectFromVariant won't convert VT_VARIANT

Initial Comment:
Any attempts to use the function PyCom_PyObjectFromVariant with an input variant of type VT_VARIANT will fail with "E_OUTOFMEMORY."

Should this function recurse until it finds a different variant type underneath?

IDispEventSimpleImpl clients from ATL will handle this case correctly, does that mean this is a bug :-)?

I'm afraid this appears invalid.  I made a patch to the test suite, which
does work correctly for in-process clients - but fails with E_INVALID_PARAM
when executed as a LocalServer (ie, as an external process).  It appears
the COM marshaller is raising this error, implying it doesn't know how to
move such a variant between processes.  If anyone can find evidence to the
contrary, please re-open.
File Added: variant_in_variant.patch
