No, we can not simply not release keys after resume from suspend, as
this leads to keys being stuck. Consider you are holding an 'I' key on
your external USB keyboard and close your laptop's lid. Then you release
the key and leave. Later you come back, open the lid waking the laptop
and observe endless stream of 'I' in your open terminal.

Maybe we should release the keys during suspend time? I am not sure how
Android infrastructure will react to this though...

Thanks.
