No. What I wanted to say is that the gui is inactive while an event callback
is processed. So the Map-event callback should only be used to initiate the
network activity but return immediately afterwards.
(not polling/waiting for the end of network transfer).
Different events/callbacks or similar should be used for monitoring.

But, of course, Fredrik Lundh's proposed method is better
(I did not know this one), if the application allows for network
activity to finish with the gui being inactive.
