Killing it the OS level would probably take care of it in a hurry.

Hi List,
I've got a production database that currently has a terminated session
stuck in the rollback state and v$session_wait shows it is waiting on
'latch free' for the 'cache buffer chains' latch. This hung session is
holding several locks that are blocking other users so I'd like to get
it cleared out ASAP, but I'm not sure how to do that. V$transaction
only shows 69 for used_ublk and it's not changing. I've already opened
an SR and am awaiting Oracle's response and also still researching &
troubleshooting on my own, but thought I'd see if any of you folks have
an answer or any suggestions.
Thanks,
Brandon
