Yep, that's a problem.

Why doesn't

DEBUG(DOUT << foo.getName() << "\n");

work?  That's how I've always done it.  A bit redundant perhaps, but it works.

In any event, errs() is probably nicer.  I'll have to see if I can do some of
the tricks I did with DOUT in these patches.  I think so, but I may be asking 
questions in the future.  :)
