Maybe the emissions channels belong in the widgets

One of the basic hassles with launching a window is that you have to create it, then hook up to the signals of interest, then tell it to show itself and really go. This is to avoid a race condition where it shows and triggers a signal prior to getting an emissions channel hooked to that signal. What if the windows had their own emissions channels? They could then avoid the race condition and the back and forth by buffering any interrim emissions... take a look, see how it feels.
