Turned out I got lucky previous time.

This time I went to the other AP, spent some time under it, roamed back and 
WiFi didn't disappear. I didn't even lose XMPP connections in the process. 

Maybe debug printing (which prints a lot) managed to introduce some extra 
delays into some race condition.

I hope I will have time to test this more on Monday. Tomorrow I will be 
using WiFi less than usual.
