Hi Simon,

If I understood you correctly that one (lazy) way is to use ecos target
definition files (.tdf files).  You can put Tcl code there (= what you
need).

My brief test was

  % cat >test.tdf<<EOF
exec notify-send Hello &
exec gksudo &
puts hello
EOF

  % watchdog2 -io -t test.tdf

and it worked as I could expect. I saw/got all things.

Well, it looks like a hack. But, as I said that is one and lazy way to
get the needed things in Tcl/Tk (=quickly).

Also, IMO, the same things can be done through .gdbinit.
