Uses of UninterruptibleLockGuard indicate places in the code that do not comply with MongoDB's requirement that all operations be interruptible at places where they block to wait for resources. Every one of them is a potential future deadlock, and adds complexity to other parts of the codebase. We should reimplement codepaths that depend on UninterruptibleLockGuard so as to be interruptible.
