first I've realized it is pretty unaltered no matter whether mem=8M or mem=192M. Next unexpected observation was apache with 5 preforked childs starting within seconds (at mem=8M) while sendmail needed 3 minutes or so, even with mem=192M. So I started to execute everything from the initscripts by hand, step by step. Result: it's not VM-related! Several processes (newaliases e.g.) are blocking in do_poll on udp socket for minutes - probably until timeout. This behavior started from 2.4.0-t9p8 onwards. Had to hack the box' config a little bit, but now it's ok (read: working, but not yet understood). So for me with 2.4.0-test9 (final) on UP there is no VM-related deadlock anymore (except the rather esoteric swap-to-file-on-ext2-on-ramdisk thing)
Sorry for the noise wrt the init-hang!
Btw, does anybody have an idea, which change (sysctl interface f.e.) on t9p7->t9p8 may have caused this? Probably I should try to write a test program to gather more information...
