[R] Memory Issue

I'm new to R and there is something I'm missing about how it uses
memory. I'm doing a simple query (using RODBC package) and immediately
set the data.frame to null close the connection/channel and explicitly
call to the garbage collector (gc()) however when I look in the task
monitor I see both "VM size" and ""Mem Usage" increased every time (for
the RGui).

I tried this on different configurations: windowxp64 / windowsxp and R
version 2.4.1 and 2.5.1. 

What I'm doing wrong?
