XEmacs has gone for Tramp, two years ago. I will check whether this
works for Tramp, but it must wait a little bit. These days I'm concerned
about the smb method. Recent smbclient, with all combinations of
SMB1/SMB2/SMB3 protocol versions, client and server, is a disaster for
Tramp. I must puzzle this out, somehow.

After that, I will see what I can do with accept-process-output.
Avoiding timeouts promises speedup. Let's see.

Best regards, Michael.
