Mmmm, I seem to have put my foot in it.  I will admit that I am beyond
my depth in dealing with the signals tests.

Perhaps we should move all the signals tests to a new subdirectory
gdb.signal, and delegate someone else to be senior maintainer for
that subdirectory?  I would feel competent to be junior maintainer.

If we don't do that, then I'm going to try something new in gdb
maintainership: delegation.  I'll ask for 2 or 3 expert volunteers,
and I'll approve a signals patch just when there's unanimous consent
among the experts.

And I've made a note to read up on signals tests.
