Comment (by unode):

 PS: On your patch above if I use:

 {{{
 #!diff
 -        printf("%s: cur: %d\n", name, lim.rlim_cur);
 -        printf("%s: max: %d\n", name, lim.rlim_max);
 +        printf("%s: cur: %lu\n", name, lim.rlim_cur);
 +        printf("%s: max: %lu\n", name, lim.rlim_max);
 }}}

 I get correct values from the test program, both for AS and RSS.
