These are not exclusive.  There's nothing in the zope.testrunner
integration that keeps the buster.js tests from being run any other
way.

Do these provide for setup and tear down of the browser slave?  That's
the primary value I was aiming for in buster-selenium, it re-uses
selenium tools to control the browser slaves and uses zope.testrunner
layers to ensure cleanup and also to share browser slaves between
tests (massive speedup).  The final value is that developers get JS
test failure feedback in bin/test.
