Yes: I have a script that checks out a "sandbox" from the repo, then
tars it up. Each test iteration then:
* Ensures there is nothing of an old sandbox (directory) around.
* Unpacks the pristine copy of the sandbox.
* Dives into the sandbox & performs a measured build.
* Exits the sandbox (and removes it).
