When rendering an image with Radiosity, it would be beneficial to me
(strangely enough) if I could save the image prior to the final trace.  Is
there a way to halt rendering and simply save a given pretrace render?

Try adding save_file "file_name" in the radiosity block. This will save the data to
disk. That's 
what is used in two pass renders.
The pretrace image is NOT saved to disk. You can do a screen capture (printn screen
key) and save 
using just about any graphics application.

Right, but it's the image I'm interested in.

I'm hoping for a way to capture the image after it's completed - it's tough
to grab the screenshot at just the right time (before the final render
begins) and to do this manually for multiple images.

Thanks anyway.

You could set the antialias settings to the max to stall the rendering 
of the final pass.  I don't know how to alleviate you of doing this 
manually for multiple images though.

Thanks, Skip.  I actually tried this, and it works reasonably well for a
single image.  Perhaps I can set up an external script to take successive
screenshots for a set of images.

Hmm, I don't suppose it's possible to get povray to execute a shell command
just prior to the final trace...?  :)  Obviously not, or somebody would
have pointed this out already.
