That is what we do in Qt right now ,but currently the mechanism we have
is not  clever  enough, most importantly because it does not ever release 
unused chunks). I have choose this conservative approach because it is 
simple and it minimizes the number of memory allocations we need. 
I will investigate in the pooling approach furthermore.
