Subject0k shared?

This may be a stupid question, but I found this strange. In making a small
benchmarking utility, I made the following directory structure by mistake:

By ..... I mean this goes on and on, there were around 18 thousand
directories inward like this. A great example of the damage a bug in a
recursive program can do ;) Anyway, I've removed it now (btw, rm -rf on
this sigsegved :D).

And now for the question. My /proc/meminfo looks like this:

total: used: free: shared: buffers: cached:
Mem: 195678208 192753664 2924544 0 116613120 45502464

LowTotal: 191092 kB
LowFree: 2856 kB
SwapTotal: 353420 kB
SwapFree: 256928 kB

As you can see, there is no shared memory here. Is this something I ought
to worry about, or is it normal? I've been using the system, and since
things were lagging, I looked at 'top', and this just caught my eye.
Any reason for worry?

And if you *really* want me to, I can see if I can reproduce this, though
I'd rather not. :-)
