Achd Exit Codes

[mxgrey]

Would it be possible to have achd return different exit codes based on the reason that it quit? So far it looks like all errors return a value of 1. Examples for what would be nice to receive different codes for include:

-- No route to host
-- The correct ach channel does not exist on the client computer
-- The correct ach channel does not exist on the server computer

I have a program which is managing an array of achd processes, and I'd like to be able to tell the user the reason that the achd disconnected. This would make troubleshooting drastically easier.
