Okay. One could certainly make the executables for some tests  
dependent on the executables of other tests, so if the type_traits  
tests fail to build then one doesn't build the tests for other  
libraries that depend on type_traits.

I don't think we could make chain tests based on whether a test  
*executes* correctly.
