This patch seems to mostly cure an oddity I've been seeing since 2.5.7x, or maybe very late 2.5.6x (I forget exactly when) where running 'ps aux' or 'ls -l' in an xterm (and only xterm it seems; I've tried rxvt and aterm) would more often than not result in a wallclock run time of up to two seconds, instead of the usual tenth of a second or so, with system and user time remaining constant. If I keep running 'ps aux' its output does start to become slow again, snapping back to full speed after a few more runs. Kind of an odd one.
