The previous change was causing a segfault after multiple calls to Py_Initialize() and Py_Finalize().

Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak detection. The speedup is about 25% for split() (571 / 457 usec) and 35% (175 / 127 usec )for splitlines()

think.  In particular, neal norwitz has traced an Ubuntu sparc64 crash
to the Lib/test/bsddb/test_basics.py test when opening a db with DB_THREAD.

Let marshal built-up sets and frozensets one element at a time (without creating an intermediate tuple).

Works like PyTuple_SetItem() to build-up values in a brand new frozenset.
Also, PyFrozenSet_New() is now guaranteed to produce a distinct new frozenset.

static PyObject* variables should use PyString_InternFromString() instead of PyObject_FromString() to store a python string in a function level static var.

it's useful outside of rational numbers.

This is my first C code that had to do anything significant. Please be more
careful when looking over it.

Handle that situation where we catch socket.errors.

We might still need to close after the for loop if flushing 6! times still
doesn't cause the signal/exception.

Many of these exceptions are due to resource unavailable, so the
existing code should be able to handle many more spurious errors.

It's system dependent.  This might fix the problem with test_rfind failing.
