Eric Snow <ericsnowcurrently at gmail.com> added the comment:
Perhaps PyImport_GetModule() should aquire-release the module's lock before the lookup? This would effectively be a call to _lock_unlock_module() in importlib._bootstrap.
The alternative is to encourage using PyImport_Import() instead, like the PR has done. In the case the docs for PyImport_GetModule() should make it clear that it is guaranteed that the module is fully imported yet (and recommend using PyImport_Import() for the guarantee).
Either way there should be a new issue for the more general change (and it should reference this issue).
