I think the following warning started to occur when I added the CLONE_NEWPID flag to the call to unshare. It doesn't seem to cause a problem at the moment, but it may well be a hidden danger.
root@ubuntu-xenial:/vagrant# ./container run /bin/bash

Maybe this is related: jemalloc/jemalloc#1006
It might be worth upgrading Ruby to v2.5 when the Brightbox package is available.
