<programming> What happens when you try to store more data in a buffer
than it can handle. This may be due to a mismatch in the processing rates of the
producing and consuming processes (see overrun and firehose syndrome), or
because the buffer is simply too small to hold all the data that must accumulate
before a piece of it can be processed. For example, in a text-processing tool
that crunches a line at a time, a short line buffer can result in lossage as
input from a long line overflows the buffer and overwrites data beyond it. Good
defensive programming would check for overflow on each character and stop
accepting data when the buffer is full.
