Because the default is to do nothing. The close method is there for 
compatibility between FileStream classes (where it is defined as 
subclassResponsibility) and other Streams (which typically do nothing 
at all).

Same with RemoteFileStream>>sleep; it's meaningless for other Streams, 
so there is a default method that does nothing in Stream.
