Killing 'undestructable' processes

[Guilherme Soares Zahn <gzahn@cnen.gov.br>]

Hi there,

    this time I have a pretty quick and direct question:

    is there a way to kill those processes that refuse to die (for
instac,e netscape will behave that way after a crash - and not even a
kill -9 does the trick)???

TIA
