Depending on how it's written, your code may be loading this data into
memory multiple times. If you're doing this work on a *nix machine
rather than Windows you can either use your system's process manager or
the 'top' program to watch the memory your IDL process is using. It's
nowhere near as good as having a real memory profiler, but that output
might give you an idea of what's happening.
