\cfunction{PyThreadState_Next()} allow looping over all the thread
states for a given interpreter. (Contributed by David Beazley.)
\item The C-level interface to the garbage collector has been changed
to make it easier to write extension types that support garbage
collection and to debug misuses of the functions.
Various functions have slightly different semantics, so a bunch of
functions had to be renamed. Extensions that use the old API will
still compile but will \emph{not} participate in garbage collection,
so updating them for 2.2 should be considered fairly high priority.
To upgrade an extension module to the new API, perform the following
steps:
\begin{itemize}
\item Rename \cfunction{Py_TPFLAGS_GC} to \cfunction{PyTPFLAGS_HAVE_GC}.
\item Use \cfunction{PyObject_GC_New} or \cfunction{PyObject_GC_NewVar} to
allocate objects, and \cfunction{PyObject_GC_Del} to deallocate them.
\item Rename \cfunction{PyObject_GC_Init} to \cfunction{PyObject_GC_Track} and
\cfunction{PyObject_GC_Fini} to \cfunction{PyObject_GC_UnTrack}.
\item Remove \cfunction{PyGC_HEAD_SIZE} from object size calculations.
\item Remove calls to \cfunction{PyObject_AS_GC} and \cfunction{PyObject_FROM_GC}.
\end{itemize}
\item A new \samp{et} format sequence was added to
\cfunction{PyArg_ParseTuple}; \samp{et} takes both a parameter and
an encoding name, and converts the parameter to the given encoding

\item The cycle detection implementation used by the garbage collection
has proven to be stable, so it's now been made mandatory. You can no
longer compile Python without it, and the
