where does the memory go?

[Matt Nelson <mnelson dynatec com>]

quick question:  after a night of doing nothing, memory usage on our LX164
looks like:

munch:mnelson> free
             total       used       free     shared    buffers     cached
Mem:        515112     506632       8480      34744      27728     454752
-/+ buffers/cache:      24152     490960
Swap:       523640        232     523408

but after working all day, the used memory goes from ~20M up to ~110M,
even though the memory usage of all the processes don't add up to that
much (i.e., during an idle period).  

where's it going?
