We will be lucky to see this in during 2.5. Its a pretty big change. It makes the Linux kernel preemptible. This is a fairly big move, one I don't think any of the major Unices have done. The only reason the patch is not _huge_ is because the Linux kernel is already setup for concurrency of this nature -- it does SMP. I suggest you read http://www.linuxdevices.com/articles/AT4185744181.html http://www.linuxdevices.com/articles/AT5152980814.html http://kpreempt.sourceforge.net and my previous threads on this issue, for more informaiton. -- Robert M.
