This cuts no ice.

Avahi doesn't depend on the GLIB main loop. In fact it is not
difficult to use Avahi without any real main loop at all. As a matter
of fact we offer a first class Qt3/Qt4 main loop adapter for

Avahi doesn't use any threading/locking primitives itself. However,
this doesn't mean it isn't thread safe. As long as you use Avahi from
a single thread at the same time only it is perfectly legal to use it
in a multi-threaded environment. In fact the avahi-sharp bindings use
Avahi that way. A minimal event loop is run in its own thread and
the little locking needed is done entirely with C# locking
