Sorry, had not time to work on this issue for over a month.
I made minor changes to make the patch build with the changes that happened while I was away.

I am still waiting for a good explanation for why there could be need for changing mouse cursor in a tight loop or even as slow as 60 times per second, which is common monitor refresh rate. I tested changing cursor every millisecond and it did not have any noticeable performance issues. In fact, on the linux machine I develop on, it consumed about 2 times less CPU in Chrome than it does on FF with the same test (http://jsbin.com/umiwuy/3/edit).
