Will this help? This will probably simplify/spead up the implementation of the Coda RVM (recoverable virtual memory) for FreeBSD (the generic port should work right out of the tar-file without modifications) .Threads are not necessary to compile this, but for the rest ( They're using Cthreads , no kernel threads and the sources are quite full of them).
