But then, don't I need one port per process?  There's no way for me to
telnet to port 5019 in process 2231, for example.  So do I need to hand out
a random port number in some range to each process?  

The signals avoided having to have an arbitrary number of numbered ports
open; I'm not sure which is the lesser evil.
