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:
