[$] Extending the time-slice-extension discussion

Time-slice extension is a proposed scheduler feature that would allow auser-space process to request to not be preempted for a short period whileit executes a critical section. It is an idea that has been circulatingfor years, but efforts to implement it becamemore serious in February of this year. The latest developer to make anattempt at time-slice extension is Thomas Gleixner, who has posted a new patch setwith a reworked API. Chances are good that this implementation is close towhat will actually be adopted by the kernel.
