  #3996: On Windows, PyOS_CheckStack is supposed to protect the interpreter from
  stack overflow. But doing this, it always crashes when the stack is nearly full.

-How It Works
-============
-
-Some changes were made to the interpreter:
-
-* ``sys.settrace(func)`` sets the global trace function
-
-* there can also a local trace function (see later)
-
-Trace functions have three arguments: *frame*, *event*, and *arg*. *frame* is
-the current stack frame.  *event* is a string: ``'call'``, ``'line'``,
-``'return'``, ``'exception'``, ``'c_call'``, ``'c_return'``, or
-``'c_exception'``. *arg* depends on the event type.
-
-The global trace function is invoked (with *event* set to ``'call'``) whenever a
-new local scope is entered; it should return a reference to the local trace
-function to be used that scope, or ``None`` if the scope shouldn't be traced.
-
-The local trace function should return a reference to itself (or to another
-function for further tracing in that scope), or ``None`` to turn off tracing in
-that scope.
-
-Instance methods are accepted (and very useful!) as trace functions.
-
-The events have the following meaning:
-
-``'call'``
-   A function is called (or some other code block entered).  The global trace
-   function is called; *arg* is ``None``; the return value specifies the local
-   trace function.
-
-``'line'``
-   The interpreter is about to execute a new line of code (sometimes multiple line
-   events on one line exist).  The local trace function is called; *arg* is
-   ``None``; the return value specifies the new local trace function.
-
-``'return'``
-   A function (or other code block) is about to return.  The local trace function
-   is called; *arg* is the value that will be returned.  The trace function's
-   return value is ignored.
-
-``'exception'``
-   An exception has occurred.  The local trace function is called; *arg* is a
-   triple ``(exception, value, traceback)``; the return value specifies the new
-   local trace function.
-
-``'c_call'``
-   A C function is about to be called.  This may be an extension function or a
-   builtin.  *arg* is the C function object.
-
-``'c_return'``
-   A C function has returned. *arg* is ``None``.
-
-``'c_exception'``
-   A C function has thrown an exception.  *arg* is ``None``.
-
-Note that as an exception is propagated down the chain of callers, an
-``'exception'`` event is generated at each level.
