For sheer amusement, I tried the following program on a Sun 3/80 running
SunOS (Sun's UNIX) version 4.0.3:

#include <stdio.h>

main(argc, argv)
int argc;
char **argv;
{
        FILE *fp;
        int i;

        for (i=0; (fp = fopen(argv[0], "r"))!=NULL; i++);

        printf("Opened %d files.\n", i);
}

It reports opening 61 files.

I guess SunOS isn't a "real" OS either.  :')

Yes, I know, it's on per process basis, but still...
