Well, in fact, two things remain not very clear for me : - Why are mmap()s performed *after* data segment ? => It seems they can go within, on GNU/Linux and NetBSD. - Why do we have such a default value for datasize (8.2, amd64) : $ limits Resource limits (current): cputime infinity secs filesize infinity kB datasize 33554432 kB this is HUGE ! -- Ganael LAPLANCHE <ganael.laplan...@martymac.org> http://www.martymac.org | http://contribs.martymac.org FreeBSD: martymac <marty...@freebsd.org>, http://www.FreeBSD.org _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
