I see that; but then we have to work out why the stdin/out/err filehandles need (re)initialising. FileStream class>>startUp: (true) is supposed to do it as part of the normal startup sequence but I had to add it at the beginning of my doit-file. Not to mention why does it seem to not work at all on Windows? And also, there is still the point that things are not in the requested/required order in the StartUp list.
As an extra excitement, how shall we allow for having startup files that want to avoid the UI starting up - say to support the idea of using Squeak for quick jobs as part of scripting? I'm not at all sure what a good answer would be here, it seems at first thought that we'd need either have two ways to specify the files in the commandline (say, -earlyfilein & -uifilein, which are both horrible and should not be used!) or to have some tags in the files to say where sections get evaluated - perhaps [preUI] & [postUI].
