+ *		backing memory uses a chunk size of a page (PAGE_SIZE).

+ *		If you make BKVASIZE too small you risk seriously fragmenting
+ *		the buffer KVM map which may slow things down a bit.  If you
+ *		make it too big the kernel will not be able to optimally use 
+ *		the KVM memory reserved for the buffer cache and will wind 
+ *		up with too-few buffers.
