Just a warning for the future - this is no longer true on all versions of Oracle 9 because the wait_time column is a copy of the underlying x$ timing column rounded from microseconds to hundredths. Hence the wait_time can show a zero when the actual time is non-zero.
You should depend only on the STATE column which is a decode of the basic microsecond value, and shows 'WAITING' if and only if the microsecond time is zero.
