[$] Extending the time-slice-extension discussion

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