Please *don't* suggest things like this. You *need* protection:

a) there is no guarantee the code will stay like it is now

b) when switching to IPv6, the write is *not* atomic any more

 

Don't try to be smarter than the authors of the code or it might eat you in the

future ;-)

 

Regards,

Simon
