I'm not sure disaster is the word I'd use, but in general, I agree.

Yeah, I need to release the buildout changes that makes buildout  
prefer released eggs.

Note that in this particular case, the real problem was circular

test for.  I'd love to outlaw them.  I wish we at least had a tool to  
warn about circular imports when testing.
