nit: consider is_shut_down or finalized() or is_shutting_down() to disambiguate
from WindowSelector::Shutdown() above which is a verb.

Done.

Comment?

I changed it to in_shut_down_ and I believe it's self-explanatory now.

+  bool shutdown_ = false;
+
   DISALLOW_COPY_AND_ASSIGN(WindowSelector);
 };
