This, of course, causes an infinite loop.  While php4 shouldn't be
segfaulting here (it looks like php5 just goes on for a while, and then
errors out with a memory allocation error, depending on what your memory
limit is set to in php.ini), you really shouldn't be creating these
loops in the first place. :)

If you want PHP to use include refcounting and not include a file more
than once, you probably want to use include_once/require_once in many
places where you'd be inclined to use include/require.
