When asked to -daemonize, we fork a child and setup a pipe between it and parent to pass exit status. os-posix.c used global fds[2] array for that, but actually only the writing side of the pipe is needed to be global, and this name is really too generic. Use just one interger for the writing side of the pipe, and name it daemon_pipe to be more understandable than cryptic fds[1].
