Trapping yourself in csh. (Fun with ignoreeof revisited)

[Felix Lee]

Here's something I cobbled together one day, when I discovered that csh would
let you alias 'alias'.  It's a script you 'source' that traps you in csh.
Works on 4.[23] Berkeleyish systems.

Be prepared to:
- kill yourself from another terminal.
- disconnect your physical/telnet/rlogin connection.
- crash csh.  (I don't know any fatal csh errors)
- start up an assassin before you source this script.

Did I miss anything?
