remoteproxy.py crashes under Python 3.3

[Richard-027]

When trying to run the RemoteSpeedTest example under Python 3.3, line 517 of remoteproxy.py throws the error:

self.proxies[ref] = proxy._proxyId
TypeError: unhashable type: 'ObjectProxy'

I was able to get it working for me by replacing line 516 with:

ref = WeakMethod(weakref.ref, [proxy, self.deleteProxy])

and by defining 'WeakMethod' with:

if sys.version < '3':
    def WeakMethod(self, args):
        return weakref.ref(*args)
else:
    class WeakMethod:
        def __init__(self, inst, method_name):
            self.proxy = weakref.proxy(inst)
            self.method_name = method_name

        def __call__(self, *args):
            return getattr(self.proxy, self.method_name)(*args)

(based on the fix described at http://jderose.blogspot.co.nz/2012/04/how-to-create-weak-reference-to.html)

No idea if that's the best approach but it seems to do the job
