This is a bit unfortunate as in our setup we depend on 'make images' to run tests, and if there's nothing to do, you will still have to wait several seconds for 'make images' to complete.

This step verifies access across module boundaries and should only be needed when any change in built classes.    This can be improved while this step is temporary until the module system is moving along.   Erik and Magnus may be able to come up with a simple way to check if any class is recompiled; otherwise this step can be skipped.
