[OS X; common] The quartered-circle busy indicator on Mac OS X versions before 10.2, after which it was replaced by a sort of rainbow pinwheel thingy. It was analogous to the Microsoft Windows hourglass, but OS X 10.0's legendary slowness under the Aqua toolkit made this term rather more evocative. See {Death, X of}.
