Odds are VERY GOOD that you have some kind of bad regex in your
httpd.conf which sends Apache into an infinite loop in mod_rewrite.
You will need to turn on mod_rewrite debugging and error logging and
crash the server again to find out what is happening.

One of the advantages of using $_SERVER['PATH_INFO'] in PHP instead of
mod_rewrite is that it's a lot harder to screw things up so
spectacularly.

I don't really understand this bit, but you should be able to do
something like this:
<?php
if (is_bad($_SERVER['PATH_INFO'])){
header("Location: http://example.com/nonexistent.htm";);
}
?>
This assumes that you can discern "bad" PATH_INFO from "good"
PATH_INFO and that nonexistent.htm does not actually exist -- or that
could exist and be a pretty page explaining that the URL they want
isn't there, if you don't want a true 404
