With that patch on pre-patch-2.0.31-2 this kind of command:
gunzip -c largefile.gz | egrep 'regexp'
made the system rather unresponsive. Without the patch the command does not affect the responsiveness.
I have a 66 MHz 486, 16 megs of ram. The 'largefile' was on a local ide disk and the size of the (compressed) file was 17 megs. Nothing mentionable running at the same time.
