Thanks for all the feedback.

Seems like a sound approach in general.  It seems awkward to apply
the method to this particular failure, though.  I guess one would need
extra code in regrtest.py to catch the invalid signal, for a start.

Thanks, Martin.  I think I've pretty much run out of time to
pursue this particular problem for the moment;  I may return
to it later.  It's good to know that these options are available,
