This test is focussed on correct handling of `docker run --cidfile`

Can we assume that the docker being tested always has this fix if the BZ is resolved?

It might be more correct to add a config. option for like "BZ1131592_fixed_in_ver", then apply workaround if current docker version is ``< BZ1131592_fixed_in_ver``.  There's a small chance of a fix being pushed upstream and not accepted, but that's beyond our control.

I know this is a PITA to need to do this stuff, I dislike it also, but I think it's just a reality we need to accept :cry:
