I just had to restart x because I was playing with keyboard layouts, trying 
to get the alt keys to properly type the 3rd level chars and screwing it 
all up, and when I had done the restart, that line in slabinfo was 
somewhat reset:
[root@coyote root]# grep buffer_head /proc/slabinfo
buffer_head        46789  78858     48   78    1 : tunables  120   60    
0 : slabdata   1011   1011      0

And frankly I don't know enough about it to state it as a fact.  Time will 
tell though.
