Well I didn't see the queue-2-is-stuck error while testing that patch
for a few days (mostly by disconnecting and reconnecting to my wlan
through clicking a GUI applet).

That being said, since a day or two I'm again running without that patch
and also haven't noticed that error. So perhaps the jury's still out on
this patch ...

Maybe I should again try suspending and resuming in a loop. But that
raises the chance of suspend/resume bugs influencing the results.
Testing bugs like these (in network code, only triggered every now and
then) apparently isn't easy.
