Web spiders crash my server when indexing threads in threaded view - some of the have 50 and more pages. Apache child process CPU usage went up to 90% and it ate all of the available memory on the system (it's a virtual server).

For now I solved this by disabling threaded view in view.php and showcat.php. I also have to find where those links to switch views in header are generated - but this is more of cosmetic nature (I would appreciate if somebody could direct me to right file as nofollow there could solve the problem).

This should be fixed:
a) include option to disable threaded view
b) fix threaded view generation
c) for SEO purposes add nofollow to that Threaded view link
