Attached is the patch (based on the patch used in FreeBSD) that should 
remedy the below mentioned issue, is it 
possible to review it and merge it in if it is descent enough?
Though, importing 9.3.1 would be nice as well, it doesnt resolve the issue 
named below but fixes some other important bugs.
Regards,

Mipam.
