No need to... the system will free the cache if it needs the memory for
running programs.  If you were to free the cache, all that would happen
is that it would fill again, at the cost of much disk I/O.  As it is,
the cache is speeding up access to commonly used blocks of data from the
disk, fetching them from memory instead of disk, an efficient process.
