What is the current state of that (-STABLE and -CURRENT)? Can you explain which problems? :) Threading on 4.x has worked for some time, although its a somewhat limited implmeentation. Its just userland pthreads so it doesn't parallelize well. In 5.x, we have true kernel-based threads, but there's some problems with certain programs. Works great for KDE however. :) -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
