This is far from trivial to implement in the kernel - I wouldn't count on it 
happening in anything approaching a reasonable time frame, and I'd bet 
against it being done at all.

If we want to be able to increase the priority of a thread, I suspect that the 
only reasonable way to do so (that stands a chance of being done) will be by 
means of either a helper process that runs as root or a kernel module, and I 
would lean towards the helper process as being the preferable solution.
