Please don't implement tests that target a specific implementation, 
especially for core classes. Spend the time to make the tests work 
everywhere.

For what it's worth, though, ENV is required by *lots* of apps and 
script in Ruby. You're going to need to have it working anyway. As for 
time-zone tweakage...anything that's a side effect of setting ENV should 
probably be modified.

You should also talk to the rubinius guys about how to run the specs 
such that they filter out things IR might never support.
