Im having a memory management problem. I have 2 ublas vectors

Vector A = vector<V1 >
Vector B = vector<vector<V2 > >  : first vector level size is 2^22

where the data types both V1=vector<int> and V2 are vector<vectors<int>> and
the size |V1| <= 2 and the
first level size of V2 <=2 and the second level size <= 10.

A grows as my program runs. B also grows but only the second level.

I run in windows and when i check the memory usage,
it seems to be around 90,000K when the exception throws. I dont really
have a good feel for these figures, so I compared to my firefox
browser, which seems to occupy approximately the same amount of
memory, hence i concluded that not alot of memory is used. My
computers have around 1/2 Gb RAM. I do not see the typical OS slowdown
which accompanies alot of paging.
