    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.

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.
