Running top, is it possible for the numbers on the memory line to exceed 
the available physical memory?
I'm talking about active, inactive, wired, exec, file and free.
Of these, if I just sum active, inactive, file and free on one of my 
machines, it definitely exceeds the available memory I have, which 
surprised me. Actually, just summing active and file results in more 
memory than I physically have.
