Hi Tony,
No -- we don't really need these here, but we thought that 
it would be an easy way for the user to set them -- esp the 
 CACHE_LIMIT.  We can actually remove themi, since it's not 
 going to change very often, and add it to plat data later.  
I'll revise the patch.  BTW, Are you going to be the one to 
 merge this code?
