Hmm, I don't think this is a good idea. Firstly, the commit() function
does something similar. (and does it the real way, i.e. it is indeed
atomic) Admittedly though, it works only once after creation of the entry
group. Secondly, Avahi accumulates multiple changes into a single
packet anyway. i.e. you have at least 50ms or so to pass your TXT
changes to Avahi and they will be sent out to the network as a single

Thus, I would prefer if the "freeze" stuff is dropped from your code
before it is merged into avahi-glib. It duplicates the functionality
of underlying APIs a little and is not strictly necesary. Let's keep
our APIs small and tender! ;-)
