I'm not any more. My thought was that it would be good for performance, by
reducing the memory allocation overhead for frames enough to allow pymalloc
to be used instead of the platform

You expect to select "Build/All" from the menu (or some such),
and expect all code to be compiled. The VC build

The function the module below, xlate.xlate, doesn't quite do what "".decode

instead of having the various behaviors avilable to "".decode)
It builds the fast decoding structure once per call, but when decoding 53kb of
