drum adj, n.
Ancient techspeak term referring to slow,
cylindrical magnetic media that were once state-of-the-art storage
devices. Under BSD Unix the disk partition used for swapping is
still called /dev/drum
; this has led to considerable humor
and not a few straight-faced but utterly bogus `explanations'
getting foisted on newbies. See also "The Story of Mel" in Appendix A.
