Its an old idea and appeared for Linux in March 1998: Little project from
Philipp Reisner called "mergemem".

http://groups.google.com/group/muc.lists.linux-kernel/browse_thread/thread/387af278089c7066?ie=utf-8&oe=utf-8&q=share+identical+pages#b3d4f68fb5dd4f88

so if there is a patent which is relevant (and thats a question for
lawyers and legal patent search people) perhaps the Linux Foundation and
some of the patent busters could take a look at mergemem and
re-examination.
