Description
Currently, we lock each individual loader object with its own lock. This can result in deadlocks, when loaders call into other loaders in the process of loading.
Instead, we want to try a single, central, high-level lock, perhaps in the base load function, that is tied to the environment/loaders object. So only one thing can be loaded for a given environment at a time. This should avoid deadlocks.
We'll probably want to try profiling this a little, but it should avoid the issue that is currently making multithreaded with environment caching unusable. See SERVER-2860 and PE-30479.
This solution is an alternative to PUP-10958.
