I've tried the archives and my memory and not found any answer: Does this mean we have a usable API for internal kernel threads? Does this involve full use of nice-levels, so I can create a thread that does data-structure optimization and not having it block more critical operations? (Context: I'm looking at some advanced firewall optimizations that will take a lot of CPU to compute, and that it would be nice to use otherwise idle time for.) Eivind.
