Ok, having run some more tests on here - it appears it may be Xen 
(virtualisation) related.

I had forgotten the 10.3 box I was testing on was a virtual machine. It 
appears the same test on a 'real' 10.3 box succeeds (as it does on the 9.x 

However, a virtual XenServer FreeBSD 10.3 instance has the problem... I'll 
kick it over to -xen to see if anyone there can think of anything...

Incase anyone else encounters the issue - as a work around removing 
everything bar '' in '/etc/resolv.conf' does work - i.e. Unbound 
will correctly pool the forwards you set it up for - if one disappears, 
name resolution continues.

Very strange... Thanks to all who replied,
