Gosh, you have to go into a program?  I just discovered tonight, while
'adb'ing a stripped object (DON'T ask why I would want to do it--object
licensees have to do many things a respectable source licensee wouldn't
*dream* of), that I can trash the kernel by simply trying to single-step
through a system call!

I'm running Xenix 3.0b on an Altos 586.  I'm curious if this will happen
on an AT or XT, but please...backup and 'sync' your disks if you're willing
to attempt to make this sacrifice for the expansion of humankind's knowledge.

If you've an Altos running Xenix?  I dunno...maybe make 'adb' executable
only by root?  (heh, heh...)
