    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;

-	if (...premature_exit...) {
-		PyErr_SetFromErrno(PyExc_IOError);
-		return NULL;
