I don't love that the default test order was changed. For our use case that isn't good, but I can just delete the `.lit_test_times.txt` file and get the old fixed order. (the reason why having a fixed order is good is because of timeouts. Also, slow tests often consume more memory in our setting, so it's not good to run all the slow tests at the same time).
So I'm just referring to the final summary, yes.

No, I'm running lit and dumping into a file. sorting is not as easy as piping through `sort`, as I'm running with -vv (required). Anyway, sorting the list on lit side should be 1 line for some that knows where that line goes :)
