IMO changing the code is best. Otherwise, IIUC, there is no way one can
force redisplay from a lisp program.

Here is an example of the need of a way to force redisplay:
I have an Emacs lisp program that I use to copy files from one box to
another. It shows in a buffer the list of files to copy and marks each
file as it is processed. If I switch away from the Emacs frame and back
again, the display is no longer updated (except for minibuffer
messages). Until now I did not know why, but now I see that some window
manager event stops (sit-for 0) forcing redisplay.
