:buzz: vi. 1. Of a program, to run with no indication of progress
and perhaps without guarantee of ever finishing; esp. said of
programs thought to be executing tight loops of code. A program
that is buzzing appears to be {catatonic}, but never gets out
of catatonia, while a buzzing loop may eventually end of its own
accord. "The program buzzes for about 10 seconds trying to sort
all the names into order." See {spin}; see also {grovel}.
2. [ETA Systems] To test a wire or printed circuit trace for
continuity by applying an AC rather than DC signal. Some wire
faults will pass DC tests but fail a buzz test. 3. To process an
array or list in sequence, doing the same thing to each element.
"This loop buzzes through the tz array looking for a terminator
type."
