A stack overflow problem.

[R. Clayton]

I am running this

  $ guile -v
  guile (GNU Guile) 2.0.9-deb+1-1

a Debian testing system updated weekly.  I did this

  $ guile
  GNU Guile 2.0.9-deb+1-1

  Enter `,help' for help.

  scheme@(guile-user)> (naughty)

I'm thinking the second call to naughty should give me another stack overflow,
rather than aborting guile.  On the other hand, maybe I didn't reset the system
properly after the first stack overflow.  Which is it?  If it's the latter,
what's the proper reset?
