- Use readonly object as lock
Info from stackoverflow:
If I want to be sure that it will be locked for all threads inside my
application:
The lock object has to be static, if it locks access to static state.
Otherwise it has to be instance, because there's no need to lock state of
one class instance, and prevent other threads to work with another class
instance at the same time.
everyone says that the object has to be "readonly" I didn't found the
reason
Well, it doesn't have to be. This is just a best practice, which helps you
to avoid errors.

When using http proxy, this will cause distinct latency
if we are trying to resolve localhost.
Currently it's unnecessary to do that because our privoxy
doesn't listern on ipv6 address, so it's ok to hard code
the ipv4 address.
There is a plan to add a cache to record the ipv6 connectivity
so that we needn't to try both ipv4 and ipv6 every time when we
attempt to connect a DnsEndPoint.
Socket.ConnectAsync will create socket and handle the address family
itself. This solves some compatibility issues on win7.

-Use dual-mode socket & DnsEndPoint to handle all domain name connection.
-Move all socket creation into one single function.
So that we could treat domain name just like ipv4 & ipv6 address.
This also solves the async domain solving problem because the os will
hanlde it for us.
