Alright. My original misunderstanding was that the
zombies only happen on solaris and that is fixed
with sigaction now. But it is of course correct
that for other platforms, too, we don't want to
risk that. Thanks for the clarification!

Pushed to autobuild.

I hope nobody is upset that I bypassed the
review request to Volker and Andreas, but I was
also involved to some extent in looking at the
failures today and was delighted that you came
up with a fix so quickly. And I am sure they will
also have a thorough look tomorrow, even if it
has reached master already... :-)
