deal with occasional docker error
deal with occasional docker error

This is a workaround for a docker issue which causes my programs to crash every few days.

Every few days, `docker run` produces an error that looks something like this:

    Error response from daemon: device or resource busy.

In the syslog, I see a message like this:

    dockerd[6467]: time="2017-06-02T03:01:49.448553334-04:00" level=error msg="Handler for POST /v1.27/containers/create returned error: device or resource busy"
