    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;
+    }
 
    An alternative is:
 
-	Py_BLOCK_THREADS
-	if (...premature_exit...) {
-		PyErr_SetFromErrno(PyExc_IOError);
-		return NULL;
-	}
-	Py_UNBLOCK_THREADS
