Log: rfork(2): Discourage rfork_thread-like approaches. Calling rfork_thread(3) does not interoperate with pthreads and global state is not properly protected. Remove the BUGS section suggesting LinuxThreads entirely. With the current pthread library libthr, all threads are kernel-level entities so there seems little reason to use LinuxThreads.
