After reading this I wasn't clear whether the 30 second per process limit was 
imposed on CPU usage or elapsed time. I ran the following test that confirms it 
is CPU usage.

The iRev file:

<html>
        <head>
        </head>
        <body>
                <?rev
                        put "<p>I started at" && the date && the time && "</p>"
                        wait 120 seconds
                        put "<p>I finished at" && the date && the time && "</p>"
                ?>
        </body>
</html>

The result:
        I started at 8/13/10 6:30 PM

        I finished at 8/13/10 6:32 PM

Personally, I think a 30 second cpu usage limit  per process to avoid looping 
process is very reasonable and should rarely be an issue when serving web 
pages. It could possibly be restrictive for server based tasks though.
