I don't understand what the purpose of this experimentation is. What exactly do you want to find out with these "experiments"? Instead of making a change that we might want to completely revamp (or, worse, get stuck with an ugly API because it's too much trouble to revamp), why not just adopt Stefan's very reasonable plan: > I think the right way to do it is to change the multi-tty code's > handling of environment so that it preserves the old behavior (and > probably breaks some of the multi-tty support), then merge into the > trunk, then try and fix the multi-tty part of the breakage.
