I don't much like this approach, I'm afraid.

* It's more serialised that necessary
* The iteration is distributed over bunches of scripts
* You can't set up heterogeonous systems
* It's nearly-duplicating functionality from sg-run-job
* The logfiles from the different guest operations are mixed up
* The multiple guests are conflated into a single cell in the
  test results matrix

sg-run-job already knows how to parallelise operations on multiple
hosts.  It wouldn't be too hard to make it capable of doing these kind
of stepwise operations on multiple guests.

Thanks for asking!

How's your Tcl ? :-)
