AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site.
These files are a subset of the python-2.7.2.tgz distribution from python.org. Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.

+The idea is that you can import these modules while in the interpreter
+and call the leak function repeatedly. This will only be helpful if
+the interpreter was built in debug mode. If the total ref count
+doesn't increase, the bug has been fixed and the file should be removed
+from the repository.
+
+Note: be careful to check for cyclic garbage. Sometimes it may be helpful
+to define the leak function like:
+
+def leak():
+ def inner_leak():
+ # this is the function that leaks, but also creates cycles
+ inner_leak()
+ gc.collect() ; gc.collect() ; gc.collect()
+
+Here's an example interpreter session for test_gestalt which still leaks:
+
+>>> from test.leakers.test_gestalt import leak
+[24275 refs]
+>>> leak()
+[28936 refs]
+>>> leak()
+[28938 refs]
+>>> leak()
+[28940 refs]
+>>>
+
+Once the leak is fixed, the test case should be moved into an appropriate
+test (even if it was originally from the test suite). This ensures the
+regression doesn't happen again. And if it does, it should be easier
+to track down.
