user/3104: Propolice katch kauth. (Patches and testcase).

On i386 it works because the heap is dirty, on sparc64 it dosen't work because the heap is clean and loop goes on forever.

Patch to fix this.

This fixes the test case on i386, and reveals another bug on sparc64.

Testcase:

#include <stdlib.h>

/* Fixed in NetBSD */
/* /usr/src/lib/libc/stdlib/random.c:1.20 */

int
main(int argc, char **argv)
{

    int len = atoi(argv[1]);
    char *foo = malloc(len);
    char *oldfoo;
