I think we could improve the javadocs here:
registerTempFile should be renamed to registerTempDir (and probably be
package-private).
The usual idiom is to do:
File tmpDir = _TestUtil.getTempDir("work"); // this 'registers' it for
deletion, but does not make it
// make the directory
// put stuff in it
if you then really need a unique temp file within that directory you
would just call _TestUtil.createTempFile(..., tmpDir)
so that it creates it in your already registered dir.
