There are 2 on Linux too, it's just that one renames itself SCREEN so
your grep probably misses it.
You could think of it as a client and a server. The server portion stays
around and does all the work. When you detach, the client dies but the
server stays around holding the ptys and children. When you re-attach,
you get a new client but the server is the same.
Make sense?
