NACK to this - cleanup should be done in the RPC classes

With this patch, the socket files could be removed successfully.

But it looks to me virNetSocketFree already unlink the socket files,
it's weired
the unix socket files still exists after daemon shutdown. So, this patch
might be
not quite right.
Yes, that suggests that virNetServerFree or something that
it calls is not cleaning up properly. It could be a missing
free somewhere, or a reference being held open.


It looks to me the "ref" is right from the debug log, (not missed somewehre).

It might be desirable to add an explicit virNetServerClose()
API which closes all sockets&  unlinks them, separately
from virNetServerFree, so we ensure cleanup even in the event
of a reference count being leaked

Yes, agree.
