    May now be wrong rather than definitely is wrong was my point, its now 
ambiguous due to the change to an interface for the event type...though I do 
wish I had just never bothered making the comment :)
    Context is probably more interesting, in that as it has been used it was to 
tie a particular proton object to a particular non-proton object for reference, 
so I can see there may be cases where you actually wouldnt want to de-dup for 
equivalent contexts and so using equals() instead of == could actually be wrong 
for the context.
