Note: Developers writing applications for OS X do not need to incorporate
this code into their applications, since OS X provides a system service to
handle this for them. If every application developer were to link-in the
mDNSResponder code into their application, then we would end up with a
situation like the picture below:

  +------------------+    +------------------+    +------------------+
  |   Application 1  |    |   Application 2  |    |   Application 3  |
  +------------------+    +------------------+    +------------------+
  |    mDNS Core     |    |    mDNS Core     |    |    mDNS Core     |
