pid = fork { p File.realpath "/" } Process.waitpid(pid) objc[82573]: +[NSPlaceholderMutableString initialize] may have been in progress in another thread when fork() was called. objc[82573]: +[NSPlaceholderMutableString initialize] may have been in progress in another thread when fork() was called.
