Yup, it's ready.  Stress tests run for several hours without bugs,  
last I worked on it.  I had an idea of automatically converting  
failing stress tests to repeatable tests, but by the time I had the  
idea, the stress test wasn't failing any more.  That was really the  
only thing holding me back from releasing.

To release it responsibly now, someone needs to claim maintainership.
