[freenet-dev] 0000389: PacketSender has to wait on blocking DNS requests

[David Sowder (Zothar)]

It's pretty much covered in bug #389, but PacketSender shouldn't have to 
wait for DNS requests to complete.  This could be part of our BACKED OFF 
problem and why not everyone is seeing the problem the same way (since 
not everyone will necessarily have peers with DNS problems, most notably 
non-existent domains, which Java doesn't seem to negatively cache).
