    Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

    Register a task to run when closing is initiated, or run it immediately if closing is already ongoing. Unlike runOnClose, this method does not guarantee that this task will have run by the time the LifeCycleManager's closeAsync method completes or AutoCloseable's close returns.
