How can the memory be freed?

["Mueller Anna" <xiaokatze hotmail com>]

Hello Everybody,

I am writing a c++ programm with Gtkmm2.6 and Glibmm2.6.In this Programm I 
used the Gtk::TreeModel to create a TreeView and I used the Gtk::ListStore 
to show a list containing 6 columns and 100 rows.
Now the Problem is:after the list cleared and updated in 10 times,all 
memory was "eat up"--which observed by sar.
I have tried to solve this problem by disconneting the TreeView from the 
TreeModel,the problem still exist.
Can somebody is so nice to give me some hint to solve the problem?
Thanks so much!

Anna
