Cur and paste from top(1), when sorting by mem usage would be helpful.
Following what Jeff Taylor said, 18932K + 45920K = 63.3MB (a bit over
half your total RAM) used up by disk buffering.
What does it look like immediately after you boot? (Don't forget
to sort by RAM usage with the M key!)

Bytes of object file size. Any mem used by them is not recorded.
