Hmm, so this system doesn't support sockets?  Or did you disable
channels manually?

I'll add a few #ifdefs.  However, we should probably connect
stdin/stdout/stderr of a job without channels to something.  /dev/null?
It's one of the options that's not implemented yet.

We should probably also support channels with pipes only, without socket
support.  Need another feature for that...
