There are a bunch of changes required to make this work: - in miner: allow unregistering agents, fix RemoteAgent.Stop - in eth/filters: make FilterSystem.Stop not crash - in rpc/comms: move listen loop to platform-independent code Fixes #1930. I ran the shell loop there for a few minutes and didn't see any changes in the memory profile.
