[dm-devel] lvmetad doesn't terminate with SIGTERM if thin volume used

After upgrading to systemd v231, my shutdowns/reboots have a 90 second
delay at the very end.  Linux kvm 4.6.4-1.

After I looked into it, I found it's due to lvmetad never terminating
when receiving a SIGTERM, and after 90 seconds, systemd performs a
SIGKILL.

systemd 231 (commit d4506129) changed the timeout on sending a SIGKILL
after a SIGTERM from 10 seconds to 90 seconds.  I think this bug has
been around for quite a while, because I've noticed shutdowns had
about a 10 second delay at the same spot that now has a 90 second
delay.

With lvmetad running with "-l all", a systemd debug dmesg log through
shutdown is attached, after running it through "grep -i lvm2".  The
full (4MB) version is here:
http://45.63.106.241/share/lvm2-lvmetad.shutdown-log2.txt

This also happens if I attempt stopping lvm2-lvmetad.  Attached is
information showing that.

Also attached is the minimal steps I used to cause the problem, using
one disk and EXT4.

If during the install I combine the 2 lvcreate commands into a single
one without using thin pools, then lvmetad terminates pretty much
immediately with SIGTERM.
