1. Of a program, to run with no indication of progress and perhaps without guarantee of ever finishing especially said of programs thought to be executing a tight loop 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 arrayOR list in sequence, doing the same thing to each element. "This loop buzzes through the tz array looking fOR a terminatOR type." [Jargon File]
