[issue1325] ddb stops responding after resizing terminal window of vkernel

Greetings everyone.

When I resize the terminal window, while being at the ddb prompt inside a
vkernel, the ddb stops responding. That is, I hit keys but they don't appear at
the prompt. The vkernel is in a 'pause' state and the only way to shut it down
is by kill'ing -9 it. Mind that this only happens if I pass >1 as the number of
CPUs to emulate, so it must be some kind of SMP issue. The problem is 100%
reproducible, but I couldn't find a pattern of resizes to trigger. Still, 3-5
vertical resizes up/down usually suffice.

Cheers,
Stathis
