Yes, that should work fine.

I notice that in 2.5, WARegistry>>unregisterExpiredHandlers has this 
comment at the end:

"Send #unregistered to each in expired"

But #unregistered is in fact never sent and never implemented.  Julian, 
is there a reason for this or was it just an oversight when I merged 
your branch in?
