May it be possible that this PR introduced a lockup of the qtests that I am
encountering in this week's upstream revisions?

I tried to bisect the causing commit and came up to this PR merge. But I'm not
absolutely sure it really is, because it sometimes takes 2 hours or more to
trigger the lockup, so the relevant commit may as well have slipped during
bisection.
Last week's revisions run here for >24h without issues, right now I get
lockups of test runs after ~3min .. ~2h when running the qtests in an endless
loop:
#/bin/sh
i=0
while true; do
i=$[$i+1]
echo '**************************************************'
echo "* RUN $i *"
echo '**************************************************'
make check-qtest -j32 V=1
if [[ "$?" -ne 0 ]]; then
echo "Aborted after $i runs due to failure"
break
fi
done
