We shouldn't lock to clear an object #130313
Description
Feature or enhancement
Proposal:
Currently we lock to clear the attributes of an object because we just re-use setting a managed dict to NULL. But if we haven't created a managed dictionary then there's no need to lock the object, it's no longer referenced externally.
Has this already been discussed elsewhere?
