TestProgram uses defaultTestLoader to load tests. Calling discover() on a TestLoader sets _top_level_dir. Calling discover with no top_level_dir implictly sets _top_level_dir but only the first time: the second time it is called with a different start_dir the prior one is used.
This leads to errors like:

ERROR: test_run_list_failed_import (testtools.tests.test_run.TestRun)
testtools.tests.test_run.TestRun.test_run_list_failed_import

ImportError: Start directory is not importable: '/tmp/tmpac4uwI'
When a test tries to test the behaviour of TestProgram (or a subclass thereof).
The fix is straight forward: at the end of discover restore the value of _top_level_dir that it had at entry.
