d50d9a6a18 More code cleanup. Removing unused variables. Simplifying and shrinking
vpage to be nearly a TLB entry. Final stripping will occur with kernel
integration. More comments.

a48062f5fa Many bug fixes and changes.
Also added "locked list" - a semaphore protected list derived from list.h.

bf738c95da Added the device driver API that Axel reminded me about.
Updated the TODO list. This is 99% feature complete.

8f72c5bcf2 Fixed a bug in the vnodeManagement
Added statistics counting.
Started down the path of making various tests share one VM space.

ceb3763e56 Implemented the sharing of vnodes. Hopefully mmap and file cache and cloned
areas will not step on each others feet...
Added comments all over the place.
Bugs squished

bc6600175c Mega changes. Using hash tables.
Many bug fixes
Some formatting changes.
Introduction of vnodeManager - to allow cached, opened and mmapped files to
work together in love, peace and harmony.

a550db6753 Checkpoint. Hand examined the code and made several changes/improvements.
Doesn't crash quite as easily. Still some nagging bugs.
Partial implementation of hashTable. Need to make find use keys and do proper
memory allocation (i.e. from physPages, not new).

8aabdd2043 More improvements. Does not run all tests, though - still have some locking issues
around clone area, I think. Still, much improved...

5fb6c38b6e Another checkpoint. Big one, this time.
Changed the whole way locking was done. What was I thinking?
Many changes and cleanup ideas from Ingo (thanks!).
Not perfect yet, but much better. Still a few things left to implement
in the COW arena - mmap doesn't use it. Also need to finish the vpageManager
which will cause mmap and cacheManager to use the same vnodes where possible.

c7b613e84e Added explicit placement new. This may be a problem in kernel land, but it
basically allows me to manage memory and still use new to setup the object.
Fixed the constructors so that objects are properly setup. Tests now run.

c70c326c96 Fixed a serious bug in list.h. :-(
Improved tests to be multi-threaded. Still needs a lot more testing.
Removed the nasty global variable in test.C.

fbafb4de2b Added more tests and we now start the thread for the page cleaner.
Verified (manually) that cleaned pages are used where possible.

8985112ee5 Fixing list.h (doh!) and some smaller changes.
Improved all of the printf's to have their method name, for easier tracking

72515139f7 Updates to make creating areas and accessing bytes work. Lots of debugging
printfs, etc in here. But some bug fixes and better code.
