New submission from Géry <[email protected]>:
A `BrokenPipeError` exception is raised when the queue thread of a
`multiprocessing.Queue` still sends enqueued items to the write end of the
queue pipe *after* the read end of the queue pipe has been [automatically
closed during its garbage
collection](https://docs.python.org/3/library/socket.html#socket.socket.close)
following the garbage collection of the queue (the write end of the queue pipe
is not garbage collected because it is also referenced by the queue thread):
```
import multiprocessing
def main():
q = multiprocessing.Queue()
q.put(0)
if __name__ == '__main__':
main()
```
