Patch

I'd like Zan to look at this.

Questions:

 (a) Isn't this equivalent to trapping the entire function, now? Both calls to X11 APIs are within the scope of one trapper or another, we could just put the trapper at the top so we only need one instead of two.
 (b) It occurs to me that it's probably a bad idea to trap errors unconditionally here. We really want to ignore errors only if shutting down, right? Is there any way we can do that, or are we just out of luck and have to trap always?
