Thanks for the explanation Michael.  Perhaps the problem is people 
select hide deleted and then it doesn't seem to work.  Perhaps there 
could be a short note with the pref saying that hide deleted is 
dependent on $_prefs['use_trash'].

I think I found an option in thunderbird to force automatic expunge on 
delete:
