------- Additional Comments from Jake Nielsen <jake.nielsen.webkit at gmail.com>
To address any efficiency concerns, I ran some tests with randomly generated
test names, and a random subset of failures and errors. 
10,000 test names, 1000 errors/failures. For comparison, there are presently
1430 unit tests in the test-webkitpy test suite.
Here are the results (time measured in seconds):
