When dumping a collection, I see a log like:
2015-06-17T13:16:14.223-0400 writing finance.stocks to dump/finance/stocks.bson
This is confusing since nothing is actually written to a dump directory.
We should instead log something like:
2015-06-17T13:16:14.223-0400 writing finance.stocks to archive
or
2015-06-17T13:16:14.223-0400 writing finance.stocks to archive 'db.arc'
