Hi all, I introduced the patches to Python to resolve race conditions in lazy loading with threads. Initially, we imported threading at the module level, but that broke gevent, so we moved the import inside the load. It seems hgdemandimport turns all imports lazy, so if threading has not already been imported, it will block its own import. It looks like mercurial maintains a list of imports that cannot be deferred, so the simplest thing is probably to update/patch that list to include threading: https://foss.heptapod.net/mercurial/mercurial-devel/-/blob/80c8dcf/hgdemandimport/__init__.py#L22-61 I'll see about whether we can also do something on the Python side to consider this case, as I believe lazy-loader is looking into creating similar functionality: https://github.com/scientific-python/lazy-loader Best, Chris
