Is such a small change like this worth pushing a whole new version of
System?  As often as you're making improvements, it seems like another
change to System package is bound to be right around the corner
anyway.  Perhaps piggy-backing this sort of micro-improvement with the
next improvement to System would be good?

>   The Clipboard class implements a basic buffering scheme for text. The currently selected text is also exported to the OS so that text can be copied from and to other applications. Commonly only a single instance is used (the default clipboard) but applications are free to use other than the default clipboard if necessary.
