001 use optimized version of PyImport_ImportModule

There are two patches optimising performance of of pyg_type_lookup function which is called every time we about to convert an object of boxed type to/from python object and can create GIL congestion if there are a lot of threads involved.
Actually there is not only GIL involved, but global python import lock also. See the commit comment in the first patch for more info.
