Hi,
When running 169 in parallel (e.g. like so:
$ while TEST_DIR=/tmp/t0 ./check -T -qcow2 169; do; done
$ while TEST_DIR=/tmp/t1 ./check -T -qcow2 169; do; done
$ while TEST_DIR=/tmp/t2 ./check -T -qcow2 169; do; done
$ while TEST_DIR=/tmp/t3 ./check -T -qcow2 169; do; done
in four different shells), I get aborts:
(Often I get segfaults, but that's because of
http://lists.nongnu.org/archive/html/qemu-devel/2018-12/msg05579.html --
feel free to apply the attached patch to make them go away)

Neither of migration or runstates are my strong suite, so I thought I'd
report it before diving into it.
