Slashdotters were arguing about the fast user switching feature that is 
in OS X Panther and also Windows XP and how Apple is filing a 
continuation of an earlier patent on their particular method of doing 
it since it's based on location manager.

Here was a very funny reply to a comment:

Ask any BOFH about the "rule of thumb" for whip, cane, tawse, or 
switch.  I find that 7200 users per minute is about the practical limit.

Personally, I prefer to counterbalance two riding crops to the hub of 
an old full-height 3600 RPM 5.25" hard drive.

For particularly annoying users, I also have an RM-80 disk pack 
(14-inch platters!)  salvaged from an old PDP-11/70.  The platters spin 
at 1800 RPM, but the huge motor required to accelerate them allows me 
to spin up four bullwhips.

Moral of the story: Don't fsck with the BOFH.
