In my Emacs (GNU Emacs 22.0.98.2 (i686-pc-linux-gnu, GTK+ Version
2.10.6) of 2007-04-20 on escher) I see two behaviors:

1. Evalling the above sexp in *scratch* with C-j or in any buffer with
M-: results in what the OP reported: "produces a blank frame while the
popup dialog is active, i.e., (redisplay t) fails to wait for
redisplay to finish."

2. Evalling the sexp with C-x C-e in any buffer results in what RMS
reported.
