/* 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

   initthread() in "threadmodule.c".

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

   mechanism!
