Subject: [PATCH] test: Make gen-threads work with python3
Date: Fri, 31 Oct 2014 13:33:25 -0400
Message-Id: <1414776805-30000-1-git-send-email-jrosenthal@jhu.edu>
Precedence: list

python3 doesn't allow dictionaries to be initialized with non-string
keywords. This presents problems on systems in which "python" means
"python3". We instead initalize the dictionary using the dict
comprehension and then update it with the values from the tree. This
will work with both python2 and python3.
