Comment 2 for bug 164288

It is more severe than I thought:

If you try to shutdown then restart `bzr serve` (ie, as a system daemon), the fact that there are still open fd (ok, open socket) on port 4155 means that **bzr serve will not start**. This means we had an outage of some large number of minutes today waiting for the TCP stack to clear.

This is still occurring with bzr 1.1
