[avahi] keep avahi-browse-list uptodate

[Florian Erfurth]

Hi,
Question A:
if somewhere a host is (un)plugged from/to network (without shutdown or
stopping network). It takes very long till the host (and its services)
disappears from avahi-browser. I can resolve the problem by doing following:
/etc/init.d/avahi-daemon restart

Is this the proper way to refresh avahi-browser-list?

Question B:
Is there a way to reduce the "Timeout", till a host will be removed from
avahi-browser-list? (same example like Question A if I (un)plug a remote 
Host)
