I think we should wait a full release before even beginning to deprecate the
SWIG bindings.
Do you have any performance numbers comparing the two?

Ditto Arfrever's suggestion.
Do you need to modify any of the build files to get it to compile?
And I think it should be possible to have both the SWIG and ctypes bindings
installed and hopefully in use in the same process at the same time. So we'll
need a separate module name for these besides 'svn'.
