The optimizations I am thinking about are in pyexpat itself. It also
needs better error handling.

Expat can do namespaces for us in C.

I'm not convinced that this is a big problem but let's just say it is.
How hard would it be to rename exported object names and the final
library name. It seems like it would be useful (and reasonably doable)
to create a tool that uniqifies dynamic libraries in general. You can
get the names using object-file reading tools or by parsing the text.
