New submission from Erdem U. Altinyurt <spamjunkea...@gmail.com>:
multiprocessing.Queue() blocking program on my computer after adding 1400 entry
(depending addition size).
Tested with 2.6.2 and 2.6.5(compiled from source with gcc 4.4.1)
Using 64 bit OpenSUSE 11.2.
Output is:
-----------
....
1398 done
1399 done
-----------
and enters deadlock because Q.put() cannot completed.
No problems with basic array with lock().
Here the result after pressing CTRL+C:
