 """Tests for code execution (%run and related), which is particularly tricky.
 
 Because of how %run manages namespaces, and the fact that we are trying here to
 verify subtle object deletion and reference counting issues, the %run tests
 will be kept in this separate file.  This makes it easier to aggregate in one
 place the tricks needed to handle it; most other magics are much easier to test
 and we do so in a common test_magic file.
