The trouble is that Console::wakeup() isn't being
called for mid-Traversal damage as it is for other
damage. Even if it were, the GGIConsole probably
wouldn't handle the case correctly since it's
using select on a pipe ... but that other thread
would be buzy so both threads would lock and
there'd be a deadlock. For the SDLConsole, wakeup
would just push a new event on the SDL event queue.
