+so this is a combination of a couple of things.
+the control code was thinking it was done with recreation a little
+sooner than it was (since the recreation code was split into two
+parts, one in RecreateControl and another in WndProc (WM_DESTROY). 
+I'm going to commit a fix for this part.
+the XplatUIX11 code isn't disposing of Hwnd's like it needs to, which
+was causing events to come in (before we handled the DestroyNotify,
+but after the window had been destroyed on the server).  This is more
+difficult to fix, since we need to keep the window references around
+so that we can clear the focus/activated/caret windows when they go
+away.  this part needs more thought.
