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, esp. by applying an AC rather than DC
   signal. Some wire faults will pass DC tests but fail an AC 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."
