Do you have any numbers/stories you can share about how the FFI
performance compares? (I've dealt with libffi myself in LuaCocoa but
haven't benchmarked it. Marshaling parameters to and from ffi data
structures was quite tedious to write but I never benchmarked how that
translated to speed in practice.)
