Docker daemon hangs when rapidly spawning containers

Ref: moby/moby#13885 (comment)

Repro:

A_LOT=300 # whatever
for i in `seq 1 $A_LOT`; 
  do docker run --rm alpine sh -c "echo $i; sleep 30" & 
done
sleep 5   # give it some time to start spawning containers
docker ps # hangs

I filled it here (as opposed to just keeping it posted in docker/docker) cause the common denominator seems to be overlayfs.

See moby/moby#13885 (comment)

I am able to reproduce across all channels.

@crawford FWIW RedHat has submitted a patch on Feb 16 for LVM/devicemapper I don't know if it's relevant for CoreOS as well moby/moby#13885 (comment)

@pmoust it looks like this was fixed in the 4.3 kernel. Can you try to repro on Beta (running 4.3.6)?

We are updating to Docker 1.12.4, which contains the upstream fixes for the docker daemon deadlocks (moby/moby#29095, moby/moby#29141). It will be available in the alpha later this week. You can reopen this if problems persist.
