I do not think that noseleep attribute is a good solution as users will
have very hard time finding and activating it. If nosleep is absolutely
required, it has to be activated automatically.

However from the discussion on the 1st patch it is my understanding that
this patch was not really required, so I will not be applying it.

Thanks.
