Test 039 used to fail
I'm confused: "used to" suggests it doesn't anymore, but you sending a
patches strongly suggests something's broken.
Well, it used to fail before this series. :-P
You're right, this sounds bad. Currently, 039 does fail, at least on any
system with a /proc/sys/kernel/core_pattern passing the dump to another
program. After this series, it does no longer.
because qemu-io -c abort may generate core dumps
even with ulimit -c 0 (and the output then contains "(core dumped)").
How?
See the patches[1][2] by Mao Chuan Li. If /proc/sys/kernel/core_pattern
passes the dump to another program, ulimit -c 0 does not matter.

The problem with those patches is that they require access to
/proc/sys/kernel/core_pattern. I don't like having to run the iotests as
root.
