Re-integrate GSoC pages with the non-GSoC world.

Remove duplicates, apart from procfs, which should rather be removed from the
GSoC items.

-
-The most obvious reason for the Hurd feeling slow compared to mainstream
-systems like GNU/Linux, is a low I/O system performance, in particular very
-slow hard disk access.
-
-The reason for this slowness is lack and/or bad implementation of common
-optimization techniques, like scheduling reads and writes to minimize head
-movement; effective block caching; effective reads/writes to partial blocks;
-[[reading/writing multiple blocks at once|clustered_page_faults]]; and
-[[read-ahead]].  The
-[[ext2_filesystem_server|hurd/translator/ext2fs]] might also need some
-optimizations at a higher logical level.
-
-The goal of this project is to analyze the current situation, and implement/fix
-various optimizations, to achieve significantly better disk performance. It
-requires understanding the data flow through the various layers involved in
-disk access on the Hurd ([[filesystem|hurd/virtual_file_system]],
-[[pager|hurd/libpager]], driver), and general experience with
-optimizing complex systems.  That said, the killing feature we are definitely
-missing is the [[read-ahead]], and even a very simple implementation would bring
-very big performance speedups.
-
-Here are some real testcases:
-
-  * [[binutils_ld_64ksec]];
-
-  * running the Git testsuite which is mostly I/O bound;
-
-  * use [[TopGit]] on a non-toy repository.
-
-
-Possible mentors: Samuel Thibault (youpi)
-
-Exercise: Look through all the code involved in disk I/O, and try something
-easy to improve. It's quite likely though that you will find nothing obvious --
-in this case, please contact us about a different exercise task.
