Erlang distribution with redundant network

[Tristan Sloughter]

I did at one point. But it ended when I learned any transport for distribution must have ERL_DRV_FLAG_SOFT_BUSY flag set for the port driver. SCTP does not which causes a badarg here https://github.com/erlang/otp/blob/maint/erts/emulator/beam/dist.c#L4017-L4018
