Well, just get it working under FreeBSD with native threading (KSE) and modify the port to respect PTHREAD_LIBS instead of linuxthreads. Others can help you test on SMP, but in theory it should behave no differently than on UP. You can simulate KSE/SMP on a UP system by setting the following sysctls: kern.threads.debug: 0 -> 1 kern.threads.virtual_cpu: 1 -> 2 Let us know if you have any problems. -- Dan Eischen
