I was still getting functional test failures, like the ones you  
describe, on some machines and not others. I narrowed down several of  
the problems and they were all real bugs in Chandler caused by race  
conditions. Not all the bugs are fixed, however. You might try  
checking in your changes and watching the tinderboxes -- I suspect  
that if you didn't introduce any new bugs these race condition bugs  
might not manifest themselves on the tinderboxes because of the quirks  
of timing on the tinderbox machines.
