We need to be able to know which maniac is using ZFS or some other
weird filesystem that is going to munch as much RAM as possible
before we report it as used...
fs type is useful too...will need a mapping to the super block
magic listing.
Whether it should be 80 or 120 I'm not sure. I think i'll go
with the lower denominator as it's more inclusive.
EVAS_ macros need simplified (this might be too simple)...
