Patient: "Doc, it hurts when I do this."
Doctor:  "Okay, don't do that."

The terminal type sun-cmd is for the cmdtool program, which has a
scrollbar.  When sun's vi is run in a cmdtool, vi turns the scrollbar
off. In a ttysw with the terminal type set to sun-cmd vi appearently
attempts to turn off a non-existent scrollbar leading to a crash. The
moral of the story is to set the terminal type correctly. Alternatively
you could use a termsw instead of a ttysw.
