I am watching this situation also. We are unable to get OpenSSH to work on
NonStop since select was replaced with poll - mostly because poll is no
longer on the platform. It is emulated only, so we are getting an "Illegal
Function Argument" reported to the remote, which reports it back. Hopefully
your resolution will also work for us.
