No.

lim.rlim_max and lim.rlim_cur have type long long so thay can not be printed
using %d.

>> FreeBSD:     getrlimit: max=-1 cur=2147483647
>> NetBSD:      getrlimit: max=-1 cur=2147483647

lim.rlim_max is actually 0x7fffffffffffffff.  The low 32 bits of it look
like -1.  The high 32 bits of it leak into the next %d.
