I'm pretty sure something changed that caused this. In the past the
leaks would be reported by the parent migration-test binary, so it
wouldn't matter where QEMU sends stderr. I don't know if it's QEMU's
build environment or something on my machine.
I'm also seeing in dmesg after migration-test aborts, which didn't use
to be the case:
Process 23732(migration-test) has RLIMIT_CORE set to 1
Anyway, the redirect to /dev/null is a pain for other reasons as well,
we discussed adding an output filter step to qtest like the iotests
have, but I couldn't find the time to work on it yet.

This is silly, but I don't think is what's causing this leak. AFAIK, it
only causes problems in some very-cornery-cases when there are races
involved. I have a patch for this one as well. Again, lacking time.

Go team! Let me just put the migration pull-request out and I'll look
into this.
