Current C implementation of OrderedDict is not safe regarding using
mutating dict methods (or dict C API) like dict.__setitem__ or
PyDict_SetItem. Using them can cause hangs or segfaults. See issue24726
and issue25410. I hope your implementation will solve these issues, but
there may be others. While the C implementation still is not enough
mature, we should allow users that encountered one of such issues to use
pure Python implementation which is free from hangs and segfaults.
