During loading, the registry clears all `ormcache` data multiple times, in order to ensure consistency with the newly loaded module data. Since083c70bbb6, this was done by calling `self.clear_caches()`, with the side-effect of signalling to all other worker processes that the cache *needs* to be invalidated, which is actually untrue. If the other workers have any reason to reload their own registries, they will also clear their own cache in the process - there is no need to forcefully invalidate it globally. One could think that combining the pre-fork mode with the `-d <db>` parameter would mitigate this issue, by making all workers inherit from a fully loaded registry, In reality it doesn't work, because they also inherit from the `cache_invalidated=True` flag, that was never cleared in the master process. So despite having a fully loaded registry, the newly forked workers will signal a cache invalidation upon serving their first request. Further, in a multi-tenant setup with large numbers of databases, registries may be recycled and loaded much more frequently than new workers are starting, due to the limited registry LRU, amplifying this effect a bit. ~~ This patch directly clears the cache LRU without going through `clear_cache()`, avoiding setting the `cache_invalidated` flag of the registry, and thus not signalling to other workers. This is similar to what was being done before083c70bbb6, where the LRU was dropped like all other lazy properties. X-original-commit: 87aef4e3a36d92462454f51960abf7215c5ab7f1
