Leaking Go routine related to PeerStore

Hi,
I have a unit test that exercises the direct one to one communication using yamux streams and if the test is ran several times over, it fails and I get a dump with several hundreds of these messages.
It seems like a peer store Go routine is leaked. The test is fairly straight forward - create two peers, connect one to the other and send a message via the stream that is established and then close the stream.
Is this something you have seen before? Would appreciate any insights.
thanks,
V

This is https://github.com/libp2p/go-libp2p/issues/718, unfortunately. The current solution is to call myHost.Peerstore().Close() after calling myHost.Close().
