* particularly recommended) for other code to use these forms too.
* Only the most typically used JUnit assertion methods are defined
* this way, but enough to live with.

* discriminable from zero time, and always allows enough time for the
* small amounts of computation (creating a thread, calling a few
* methods, etc) needed to reach a timeout point. Similarly, a SMALL
* is always discriminable as larger than SHORT and smaller than
