Setting rtable 0 from >1 with ping et al

[Joe Holden]

Hi,

So - it seems that pledge will deny a change of rtable to 0 when using 
level SOL_SOCKET and the current rtable is >0, so eg if you're in table 
1 and you do ping -V0 it will fail.

Can anyone shed any light on why this is restricted?  Especially since 
the same can be achieved with route -T0 exec

Thanks!
