How is the script continually processing?  Do you mean that the page still
seems to be loading in a browser or the server processes are still going?

If it's continually loading in the browser, Jiju is on.  I ran into this
quite a bit with a faulty mod-rewrite which was actually loading a copy of
the site for every image, css and javascript file call.  Even when I fixed
that it ended up 
doing the same for any 404's.  That was an Enormous hit on the server (large
project with quite a few heavy oo classes).

If it's on the server and you're using apache, my first suggestion is to run
php in cgi mode if at all possible.  Switching from mod to cgi made it
easier to tell 'who' was hogging everything, since php runs separately (can
monitor the php executable to see when it stops)

Also, look into xdebug's automated profiling, which is incredibly helpful -
think firebug for your server.  Use KCacheGrind (linux only) or
WinCacheGrind (Win32) to process xdebug's logs.  That'll tell you Exactly
where all the time is going - which functions, which classes, etc.
