Final annoying bug... When using Amethyst's Tor alongside Orbot, if Amethyst starts first, then both Tor connections work (and you can choose which one to use).
But If Orbot connects to Tor before Amethyst does, only Orbot works. Even though Amethyst got a separate SOCKS proxy/port from the Tor library, all tor channels immediately close.
