    /loncom	loncnew 
  Log:
  Continue adding latent support for child exit when connection count 
  trimmed to zero: Allow default host for GetLoncSocketPath and 
  SetupLoncListener to be optionally parameterized with a loncapa
  hostname.  The actual server processes will typically not parameterize
  these, but the parent/master will.
