Yup.

It's gratifying to know someone's reading the checkin log.  :)

Oh, lovely, virtual base classes.  Urp.  One of the few C++ features I 
try very hard to ignore.

I'm gonna have to think about this one.  If I add the virtual base ctor 
call, it's likely to just confuse me again 6 months out.  I'll yank it, 
and we'll be back here again the next time I unleash the pedant on the 
code.  But, if I add a comment telling me why I can ignore the warning, 
that's pretty ugly, too.

Mull, mull...
