DomitaTest sometimes fails under heavy load

Symptom: DomitaTest sometimes fails the cajita-mode test 
when I'm running several other things at the same time.
The test report says something like "98/99 pass", but the
firefox window says "99/99 pass - all tests passed"

1. DomitaTest has a mechanism for waiting for async tests,
but the xpath expression was wrong, so the test could exit
while there are still pending tests.

2. Several async tests weren't marked as async.

Just to satisfy my silly pedantry, can you make this regex
  /\b(clickme|waiting)\b\s*/g

Wow.  Our test pages are going to look like a bunch of skittles.
