Hatari check for keys presses during the internal VBL handler (which 
always happen, even when SR=2700, contrary to the emulated VBL).

But in that case Hatari enters some kind of situation where no more 
instruction are executed, so cycles counter doesn't increase anymore and 
the internal VBL handler doesn't trigger, even after a long time.

There could be some kind of watchdog to detect such situation, but it 
could impact performance when everything goes right.

I might try to have a look at this if I get some time.
