It's a test server in the end. And I'm as *user* still think that test 
suite is not needed for me. It's my *user* point of view. So if this 
patch could break one or two hundreds tests -- it's not important right 
now, when we already have more than 300 failed tests on Windows. So, I'm 
don't care much as user. And I still think, that bzr should be shipped 
without test suite (in linux distros, in installers, not as sources of 
course). I even saw bug report confirmed by Robert Collins about 
decoupling tests and core lib.
