message:
  Delete faulty test that can leak a subprocess and/or hang the test suite.
  
  * bzrlib/tests/blackbox/test_breakin.py:
  (TestBreakin.test_breakin): Deleted. The spawn process may be left
  hanging around under some circumstances.
  (TestBreakin.test_breakin_harder): Get some bits from test_breakin
  to avoid reducing test coverage.
