I don't see why program would allocate memory without writing to it

I do this when I need contiguous memory, but don't know how much. Then I allocate lots of space; unused memory is cheap. The result looks like this:

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
anton    17100  0.0  0.2   6300  1196 pts/0    S+   14:16   0:00 gforth

The large VSZ is caused mainly by unused allocated memory.

So if you want to know the real memory usage, counting private anonymous mappings is not good enough.
