Q5.0.20: Is there a way to start a new SXEmacs if there's no gnuserv running, and otherwise use gnuclient?

Here is one of the solutions, we have this in a script called etc/editclient.sh.

      #!/bin/sh
      if gnuclient -batch -eval t >/dev/null 2>&1
      then
        exec gnuclient ${1+"$@"}
      else
        sxemacs -unmapped -f gnuserv-start &
        until gnuclient -batch -eval t >/dev/null 2>&1
        do
           sleep 1
        done
        exec gnuclient ${1+"$@"}
      fi

Note that there is a known problem when running SXEmacs and ‘gnuclient -nw’ on the same TTY.
