    Performs the task given by f unless a shutdown has been initiated.

    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.

    DO NOT CALL this.close as part of f, because it will result in a deadlock.

    scala.None$ if a shutdown has been initiated. Otherwise the result of the task.

    Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead. Both etf and the error are lazy; etf is only evaluated if there is no shutdown, the error only if we're shutting down.
