Can eat 100% CPU under rapidly varying network connectivity
Bug description
I'm currently on the road, and my internet goes in and out. Every now and then, my network connection will appear connected but will not actually send/receive packets. (Likely due to Wifi flakiness.) Under such circumstances, gajim will occasionally become unresponsive and eat 100% CPU. This will quickly drain my battery at a time when I most need it, which is highly inconvenient...
