I couldn't think if a better way to detect what the host system had and adding this seemed inline with the busybox check. 

The choice of running `sleep` seems like it was arbitrary and the test should use something that is under JDK control rather than a platform specific tool that can change from distro to distro. Is there any reason we don't use the `java`, something else in the image, or even something built as part of the test-image.
