Since the message confirming outgoing transfer completion is logged asynchronously, it may happen that transfer statistics may not yet be logged by the time the dig command triggering a given transfer returns. This causes false positives for the "ixfr" and "xfer" system tests. Prevent this from happening by checking outgoing transfer statistics up to 10 times, in 1-second intervals.
