	    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).

	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.
