stack puke
     
        Some processor architectures are said to "puke their guts onto
        the stack" to save their internal state during {exception}
        processing.  The {Motorola 68020}, for example, regurgitates
        up to 92 bytes on a {bus fault}.  On a {pipeline}d machine,
        this can take a while.
