unconfigured.
In the aforementioned commit, the existing behavior was changed,
I believe in advertantly, to set propagate to False if the
trace logger already has been configured. This seems to be the
opposite of the internet, and this change restores what appears
to have been the intent, and silences the tracer unless
it has been configured, in which case it will propagate.
The simplejson parser drop-in compatible with the builtin python JSON
parser, but much faster. In particular, this makes operations like
reindexing quicker.
