smart server is noisy on disconnection

I start a server, then branch from a bzr:// URL and when the branching
is done
the server raises an exception:

<bzrlib.transport.smart.SmartStreamServer object at 0x02223C90>
terminating on
exception (10054, 'Connection reset by peer')
Exception in thread smart-server-child:

    data = self._sock.recv(self._rbufsize)
error: (10054, 'Connection reset by peer')

It causes no problems and branching/pushing works fine next time again,
but
shouldn't be the disconnecting handled somehow? Or is this a
Windows-specific bug?
