Subject: 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.

+"""This test case provides support for checking forking and wait behavior.
+
+To test different wait behavior, override the wait_impl method.
+
+We want fork1() semantics -- only the forking thread survives in the
+child after a fork().
+
+On some systems (e.g. Solaris without posix threads) we find that all
+active threads survive in the child after a fork(); this is an error.
+
+While BeOS doesn't officially support fork and native threading in
+the same application, the present example should work just fine.  DC
