The number that beostatus uses for the amount of memory used includes
the memory used by programs as well as the memory used by the kernel for
buffers and such.  This is the same as the program 'free'.  If you ever
run 'free' you'll ntoice that the amount of memory used seems kinda
high, this is because it takes into account kernel buffers and cache.
