passing a stdin to docker run hangs the container

[GabyCT]

If you pass a stdin to docker run, the container hangs

$ echo hello | docker run -i busybox
sh: hello: not found
....
but the container do not gets terminated like if you use runc.

Here are the specifications that I am using
cc-runtime : 3.0.12

Docker version 1.12.1, build 23cf638
