_decimal is about 12% faster without threads, because the expensive thread local context can be disabled.
If you cached the last thread id along with the corresponding context, perhaps it could speed things up in most scenarios?
Nice. This reduces the speed difference to about 4%!
Note that you don't need the actual thread id, the Python thread state is sufficient: PyThreadState_GET should be a simply variable lookup in release builds. Regards Antoine.
