I've avoided Spork so far, but I've tried Spin[1]. Spin shaves a few seconds off but it's still agonising. I've also experimented with multiple Guard groups and other hacks to run isolated code in lib/, but a lot of the code can't be isolated (all the controllers, for example).

I imagine it would have to run tests over DRb, which I've only used with Spork before. The last mention of "cache_classes" on this list was in 2009, so I thought I'd check before I invested time in it in case there any major obstacles.

Anytime someone suggests using 1.8, a Chinchilla explodes. 1.9.3 has the "slow require" fix - please use that if it is your concern.
