The ulimit logic has been failing for me for months now and felt still ran fine. I think we don't need it any more. Also add the `-i` option for incremental runs of `felt`. It causes felt to start faster because it doesn't run `pub get`. In the future, we can also run felt from the snapshot for even faster start-up.
