Just discovered there's a bug here (in code that I wrote obviously) --
you can't pass the last argument as nil; you have to include a logger.
Otherwise if you ever get an error you'll get a NULL dereference. :-)
I think the fastest thing to do to begin with would be to create a
"null" logger that just throws away all the data. Then at some point
(possibly not in your internship) someone can think about what a
proper logging interface looks like.
