Summary: cPickle does not use Py_BEGIN_ALLOW_THREADS.

Details: This bug refers to:

python/dist/src/Modules/cPickle.c
Revision 2.54 (In SourceForge)

The use of fread (line 506) and fwrite (line 410) are not wrapped by
Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS.

This causes certain uses of cPickle in threaded programs to deadlock, where
pickle does not.
