This  small  shell-only  command  attempts  to  free unused memory and
unfragment  the memory pool at the same time.  It works similar to the
standard  'avail  flush'  command  but  prints  out  how  much  it has
recovered  and  unfragmented.   This can be a useful debugging tool to
check  for  programs which fragment memory or how much memory is taken
up by unused libraries, fonts, devices etc.  or to simply clean up the
memory pool after running a lot of things.
