drum adj, n.
Ancient techspeak term referring to slow,
cylindrical magnetic media that were once state-of-the-art storage
devices. Under some versions of 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
