Maintain a
ConditionalWeakTablecache ofRedirectproxy instances keyed against proxy root instances. If an existing proxy has been created from aRedirectwith a root instance and another proxy is created with the same root instance then the same cached proxy instance is returned.As well as being an optimisation the intention is that a system that has its instances replaced with proxies will behave more closely to the original e.g. in terms of instance equality.
