[Chandler-dev] Loading developer tools on tinderboxes?

Here are a few other options to consider:

Installing wing on the tinderbox machines, but not running tests in  
wing, so when problems happen we can wander over to the machines,  
attach and debug chandler.

Running w/wing on tinderboxes, but turning off the feature in wing  
that stops on exceptions.

Finally, I've been running functional tests on my computers at night  
and I've been finding (and fixing) rare failures. I'd suggest  
everyone try it out.
