-  The default console implementation, used by iosrv. This console implentation has
-  two reasons to exist:
+  The default console implementation, used by iosrv. This console implementation has
+  one reason to exist (there used to be more):
 
   1) To hunt for a suitable real console implementation to be used by default. On
      GUI configurations this will either be guicons.dll or econseik.dll. On text
 	 configurations this will be econs.dll.
 
-  2) To delay the creation of the real console implementation until it is known
-     to be needed. This is useful because CCommandBase creates a default console
-	 even if --console has been specified on the command line. The default console
-	 may be used by the specified console during its construction to interact with
-	 the user (e.g. vt100tcpcons uses it to tell the user which TCP port and IP
-	 address it is listening on). However, if it weren't to be used, the user
-	 would see the default console briefly appear and then disappear when the
-	 actual console is created. Delaying the creation of the console underlying
-	 the default console avoids this.
