I think #1840 is a good suggestion.  Since the layer could have multiple 
strategies, the "loadend" event might not actually mean that features 
have been added to the layer.  I think this is acceptable, not sure if 
it works for all.  This would mean that the loadstart and loadend events 
would only be about fetching remote data - not adding features to the layer.

Bart, if you are in irc range, we could discuss now there.
