I guess a realistic reflection of a process' (open) file descriptors:

	noon% ls /dev/fd/
	0  11 14 17 2  22 25 28 30 33 36 39 41 44 47 5  52 55 58 60 63 9
	1  12 15 18 20 23 26 29 31 34 37 4  42 45 48 50 53 56 59 61 7
	10 13 16 19 21 24 27 3  32 35 38 40 43 46 49 51 54 57 6  62 8

I doubt that ls has 64 open file descriptors.
