+/* Protection against deeply nested recursive calls
+
+   In Python 3.0, this protection has two levels:
+   * normal anti-recursion protection is triggered when the recursion level
+     exceeds the current recursion limit. It raises a RuntimeError, and sets
+     the "overflowed" flag in the thread state structure. This flag
+     temporarily *disables* the normal protection; this allows cleanup code
+     to potentially outgrow the recursion limit while processing the
+     RuntimeError.
+   * "last chance" anti-recursion protection is triggered when the recursion
+     level exceeds "current recursion limit + 50". By construction, this
+     protection can only be triggered when the "overflowed" flag is set. It
+     means the cleanup code has itself gone into an infinite loop, or the
+     RuntimeError has been mistakingly ignored. When this protection is
+     triggered, the interpreter aborts with a Fatal Error.
+
+   In addition, the "overflowed" flag is automatically reset when the
+   recursion level drops below "current recursion limit - 50". This heuristic
+   is meant to ensure that the normal anti-recursion protection doesn't get
+   disabled too long.
+
+   Please note: this scheme has its own limitations. See:
+   http://mail.python.org/pipermail/python-dev/2008-August/082106.html
+   for some observations.

+/* Interface for threads.
+
+   A module that plans to do a blocking system call (or something else
+   that lasts a long time and doesn't touch Python data) can allow other
+   threads to run as follows:
+
+    ...preparations here...
+    Py_BEGIN_ALLOW_THREADS
+    ...blocking system call here...
+    Py_END_ALLOW_THREADS
+    ...interpret result here...
+
+   The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
+   {}-surrounded block.
+   To leave the block in the middle (e.g., with return), you must insert
+   a line containing Py_BLOCK_THREADS before the return, e.g.
+
+    if (...premature_exit...) {
+        Py_BLOCK_THREADS
+        PyErr_SetFromErrno(PyExc_IOError);
+        return NULL;
+    }
+
+   An alternative is:
+
+    Py_BLOCK_THREADS
+    if (...premature_exit...) {
+        PyErr_SetFromErrno(PyExc_IOError);
+        return NULL;
+    }
+    Py_UNBLOCK_THREADS
+
+   For convenience, that the value of 'errno' is restored across
+   Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
+
+   WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND
+   Py_END_ALLOW_THREADS!!!
+
+   The function PyEval_InitThreads() should be called only from
+   init_thread() in "_threadmodule.c".
+
+   Note that not yet all candidates have been converted to use this
+   mechanism!
