Committed, along with additional patch for #15347.

Not done yet.  I want to do more testing, including with -n, after my 
additional patch.  I want to understand why 'interacting' seems to have 
no effect before removing it.

I identified one shutdown situation which is not handled properly yet, 
and may not have been Roger's patch either.  Gracefully shutting down 
the debugger without bad side-effects is not trivial.  But we have 
improved several cases.
