Improving the kernel/i386 timecounter performance (GSoC proposal)

[Prashant Vaibhav]

Eugene,
No I am not. Looking at it now. I'm not familiar with a lot of things
specific to the freebsd kernel actually, but familiar with tsc/timing stuff
in general and xnu in particular. After seeing this in the gsoc ideas list I
decided to apply, assuming it would map well to freebsd too.

Best,
Prashant
