I hadn't compiled any of those into my custom kernel, as per some now 
long-forgotten web page that said I should use the sysctls to reach the 
same effect.

What I'd *really* like to find is an explanation of how to set those 
numbers.  I'm using a single Xeon with 3GB of RAM and have no idea how high 
to set those, or whether a particular value is too high.  Then again, once 
I figure it out I guess I should have a fair amount of job security.  :-)
