// Net subsystem
//
// Net subsystem is a layer on top the operations sytem network apis. It
// provides an interface for accepting/creating new connection oriented
// (TCP) and connection less (UDP) connetions and for reading/writing
// data through these. The net system can manage 1000s of connections
// very efficiently. Another advantage of using the net system is that
// the SMs dont have be concerned about differences in the net apis of
// various operations systems.
//
// SMs use the netProcessor global object of the Net System to create new
// connections or to accept incoming connections. When a new connection
// is created the SM gets a ObNetVConnection which is a handle for the
// underlying connections. The SM can then use the ObNetVConnection to get
// properties of the connection, read and write data. Net system also
// has socks and ssl support.
