that's the funny part: Nothing. There is not one process from 
the subuid range running. It simply hangs before it tries to 
start the container at all. And I have no idea, why.
But with lxc-2.0.8 it works. 

I just installed and started debian wheezy, upgraded it to jessie
and finally to stretch. It works fine.

I now installed lxc-2.0.9 again, tried to start the container again
and nothing happens:

   $ lxc-start -n lxc-test -l trace -o stretch-lxc-2.0.9 -F

That's all. lxc-ls -f and lxc-attach-n lxc-test hangs, too.

I see also three processes of lxc-start:

   $ ps waux |grep lxc-start
   lxc-test 24478  0.0  0.1  51740  4232 pts/0    S+   17:16   0:00
   lxc-start -n lxc-test -l trace -o stretch-lxc-2.0.9 -F
   lxc-test 24487  0.0  0.0  51740   504 pts/0    S+   17:16   0:00
   lxc-start -n lxc-test -l trace -o stretch-lxc-2.0.9 -F
   lxc-test 24492  0.0  0.0  51740   508 pts/0    S+   17:16   0:00
   lxc-start -n lxc-test -l trace -o stretch-lxc-2.0.9 -F

That's really strange...

Best regards

Dirk
