this is not so much software related...

1) use IDL under Linux or windows 64 bits (both remove the limit of 2gb
max per process, and you have less/no "random RAM location" in use,
meaning bigger chunk of contiguous memory)
2) break your work in chunks... don't create 1 big array, but 2 small
ones etc. I often use a function that finds the available memory, and,
depending on the memory I will use in my own function, I decide what it
the max size of the array.
