New submission from Stanisław Skonieczny (Uosiu):
This bug results in raising TypeError: __str__ returned non-string (type
MagicMock)
Following program can reproduce it:
```
from threading import Thread
from mock.mock import MagicMock
def main():
mocks = [MagicMock() for _ in range(1000)]
def in_thread():
for m in mocks:
str(m)
threads = [Thread(target=in_thread) for _ in range(10)]
for thread in threads:
thread.start()
for thread in threads:
thread.join()
if __name__ == '__main__':
main()
```
For me it rasies few times:
```
Exception in thread Thread-6:
Traceback (most recent call last):
File "/usr/local/lib/python3.5/threading.py", line 923, in _bootstrap_inner
self.run()
File "/usr/local/lib/python3.5/threading.py", line 871, in run
self._target(*self._args, **self._kwargs)
File "../misc/magic_mock_str_bug.py", line 11, in in_thread
str(m)
TypeError: __str__ returned non-string (type MagicMock)
```
