BTW this should be 

		printf("soft=%qd\nhard=%qd\n",Lim.rlim_cur,Lim.rlim_max);

According to the getrlimit manpage, 

An ``infinite'' value for a limit is defined as RLIM_INFINITY.

and looking in /usr/include/sys/resource.h, we find:-

RLIM_INFINITY   (((u_quad_t)1 << 63) - 1)

See above. I believe this is working as documented.

It's in /usr/src/sys/kern/kern_resource.c
