[Python-Dev] refleaks in 2.4

[Neal Norwitz]

There are 5 tests that leak references that are present in 2.4.3c1,
but not on HEAD.  It would be great if someone can diagnose these and
suggest a fix.

test_doctest leaked [1, 1, 1] references
test_pkg leaked [10, 10, 10] references
test_pkgimport leaked [2, 2, 2] references
test_traceback leaked [11, 11, 11] references
test_unicode leaked [7, 7, 7] references

test_traceback leaks due to test_bug737473.
