OK, I've had a go at this and tried removing EVERYTHING related to the
delayed menu stuff and, as you say, it seems fine, but I barely ever
use the menus, so I could be missing something.

For the record, the menu code (or maybe it's the toolbar, but I
suspect the menus) kills GNUstep builds stone dead as soon as you try
typing anything. It looks from the debugger like Emacs is still
running, but it just won't update the screen. Turning off the menus
appears to fix it.
