overrun
 n.

    1. [techspeak] Term for a frequent consequence of data arriving faster than
    it can be consumed, esp. in serial line communications. For example, at
    9600 baud there is almost exactly one character per millisecond, so if a 
    silo can hold only two characters and the machine takes longer than 2 msec
    to get to service the interrupt, at least one character will be lost.

    2. Also applied to non-serial-I/O communications. ?I forgot to pay my
    electric bill due to mail overrun.? ?Sorry, I got four phone calls in 3
    minutes last night and lost your message to overrun.? When thrashing at
    tasks, the next person to make a request might be told ?Overrun!? Compare 
    firehose syndrome.

    3. More loosely, may refer to a buffer overflow not necessarily related
    to processing time (as in overrun screw).
