Does it take 20-100% of the CPU time nowadays (on the same hardware that
it used to take only 2-10% on)? :-)  It now has pessimizations like using
one sysctl per struct member instead of one kvm_read per struct to read the
contents of the kernel's `struct vmmeter vmtotal', despite the existence
of a sysctl for reading the struct.
