Description

E.g. if at the beginning or the end of a Lock.lock() scope, only local data is accessed, one can reorder the code to make the critical sections smaller (and hopefully improve performance).

This should probably be #[allow] until we have some experience with it.

Research direction

The issue names no file, test, or entry point. Start by surveying rust-clippy’s lint registration and existing lock-related tests; done should include a lint for unnecessarily broad Lock.lock() scopes, initially allowed, with tests covering the reported cases.
