This bug is probably fixed as part of bug fix for MDEV-8066 .
Lets keep this task open for a while to see if rpl.semisync_future-7591 fails in10.0 and if not,
close it.

The failure happened at least once on 10.0 tree after the bugfix for MDEV-8066 had been pushed:
http://buildbot.askmonty.org/buildbot/builders/kvm-deb-vivid-amd64/builds/486/steps/test_4/logs/stdio

And on 10.1, also after the bugfix for MDEV-8066 had been merged:
http://buildbot.askmonty.org/buildbot/builders/ibmz-rhel6-bintar/builds/104/steps/test/logs/stdio

It was quite long ago, but it has never happened frequently. So, it wasn't fixed by MDEV-8066 patch.
