Core and builtins
-----------------
+- Issue #1164: It was possible to trigger deadlock when using the 'print'
+ statement to write to a file since the GIL was not released as needed. Now
+ PyObject_Print() does the right thing along with various tp_print
+ implementations of the built-in types and those in the collections module.

- Issue #1147: Exceptions were directly allowing string exceptions in their
throw() method even though string exceptions no longer allowed.
