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);

|

}

|

|
||||

Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
