No, I haven't yet tested that yet. Part of the reason is that I'm 
currently very busy with other stuff, the other part is that I find the 
trunk to be in a little bit of a flux. Stuff gets rewritten and changed 
without proposals and I don't actually see through it anymore 
(understanding what's happening by reading checkin emails takes much 
more time than reading well-laid-out proposals). On some of my instances 
I get random SystemErrors now, I have to look into that.

In any case, I plan to test converting an old X3.0 instance with my 
book's code to a trunk one soon.
