>Description:
        Test runs in the gson dashboards are randomly failing in what seems to
        be an atf-run problem.  atf-run abruptly exits without any error 
message.
        For example:

        http://www.gson.org/netbsd/bugs/build/build/2010.11.30.14.08.39/test.log

        This is being blamed to the last atf import (0.12) but none of the
        changes that went in it could be responsible for this (after a very
        quick look, that is).  It is also hard to reproduce by me and pooka.

        According to gson, this might also be caused due to him switching from
        "qemu -no-kvm" to "qemu -no-kvm-irqchip".

        Need to investigate which of the two causes it is and fix accordingly.
