What steps will reproduce the problem?
1. Gather a significant number of results (>~50) from parallel future queries
as part of a request;
2. The error message below will occasionally occur - roughly once every 20
requests.
What is the expected output? What do you see instead?
The expected output is completion of the command.
Instead, the output is the following traceback:
WARNING 09 Apr 2013 14:30:02 suspended generator _count_async(query.py:1231) raised ImportError()
WARNING 09 Apr 2013 14:30:02 suspended generator helper(context.py:800) raised ImportError()
