I just did a search for "reactToGC". It appears that EProxyResolver  
(not EProxyHandler)'s reactToGC is called only as a WeakPtr reactor,  
and so it does not need to (and should not) be part of the client  

Not that you mentioned this as an issue, but gettingCloser/0 should  
be replaceable with a when-more-resolved reactor on the resolution
