My colorized listing and postprompt patch does this for Zsh-3.0.2.  You
set PPTMOUT to the number of seconds to wait before displaying the
string, and set POSTPROMPT to the string to display (including the
escape characters).

Note that this has the advantage that only commands that are running for
a certain length get displayed.  It has the disadvantage of the
possibility (very very rare when you use an xterm control sequence) of
mixing output with the running program. (not a problem if running
program sends output to a file).

See the patches on my web page, ../gjb/patches
