/* 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 RecursionError, 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

     RecursionError.

   * "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

     RecursionError 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_OSError);

        return NULL;

    }

   An alternative is:

    Py_BLOCK_THREADS

    if (...premature_exit...) {

        PyErr_SetFromErrno(PyExc_OSError);

        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!!!

   Note that not yet all candidates have been converted to use this

   mechanism!
