By the way, Jason.  I checked that information:

[root@sandbox src]# sysctl -a | grep buf
vm.buffermem = 2        10      60


Then, I took a look at the "/usr/src/linux/Documentation/sysctl/vm.txt" 
file trying to figure out how to interpret those three figures and here is
what I found:

The values are:
min_percent     -- this is the minimum percentage of memory
                   that should be spent on buffer memory
borrow_percent  -- UNUSED
max_percent     -- UNUSED

This is in a 2.2.15 kernel, so perhaps the documentation changed in newer
versions.  So, my obvious question is: are those two other parameters
usable now?  The one we seem to be interested on here is max_percent, I
suppose.
