Adding back in a loop for catching database busy errors.  It needs to be added back in other spots as well, which I'll do - but I haven't thought of the best way to break out of the loop yet, so I'm going to request some comments on that.
Discovered sqlite3_busy_handler, and got to kill some ivars and code.  busyTimeout has been replaced by setMaxBusyRetryTimeInterval: - this is a _lot_ better than adding loops everywhere.
