Now that CRIU can drop in-flight connections I get much better results
checkpointing and restarting my test container while running ab against
the tomcat server in the container: ab -n 1000000 -c 20

I am still testing with LXC using lxc-checkpoint and once every 100 test
runs I get following error:

Can this also be solved in a way like the dropping of in-flight connections?
