		That doesn't cost much, really.  The time-consuming parts are the
		measuring of text size and keeping parent output records and scroll
		bars up to date.

	    Scroll bar updating can indeed be expensive. There's an internal macro
	    in 2.0, clim-silica:inhibit-updating-scroll-bars, which can reduce output 
	    time by >25%. However, it's not an external/documented macro, and the
	    Symbolics and Franz implementations aren't compatible.

	Huh?  I wrote this macro myself before Franz split away from everyone
	else.  How are they not compatible?  What does the Franz one do now?

    It takes a stream argument (from which it gets the viewport).

Boo!  It doesn't even need one!

I guess you should simply write

  (inhibit-updating-scroll-bars #+Franz (stream)
    ...)

since all the other implementations don't require a stream argument.

	    So, is there a supported way to do this? If not, it would be useful if this 
	    or something like it could be made part of CLIM's external interface.
