This WIP release is meant to beta-test a tentative fix for the inode
exhaustion problem that was reported with DR2u5. The symptom for this 
bug is a lot of "VFS: no free inodes - contact Linus" messages and
a system that's nearly completely frozen.

Since there was lots of other work in progress, it also includes:
* minor fix for keyboard raw mode (autorepeat was still on),
* some cpu load statistics gathering,
* CPU limits and ITIMER_VIRTUAL are implemented,
* better resolution for time stamps,
* some optimizations for frequently used Mach interfaces.

Please use all the components of this WIP release together. Other
combinations might work but haven't been tested.
