I would guess that your OS is saving memory for disk I/O, your mail 
reader, your browser, etc etc and for itself (most OS's are very large 
these days).

I am glad to hear that the OS's do defend themselves - I was afraid that 
they would allow you 4 Gbytes of virtual memory on a 2 Gbyte actual 
memory machine if the swap spaces was large.  That would run really 
really badly.
