It *tells* you to close, but you can tell it to sod off.  You do this
by returning closeErr in response to the close message.  This will
leave you opened.

Doesn't work for me.  I spent two weeks converting an application to a
DA this way, and it worked perfectly in the fake debugger mode.  It
never could be made to work as a multi-segment DA, however.  Be very
careful.  I debug my DAs using MacsBug, and make them as DAs.
