1. Memory is not limiting on the box, as the memory limit I am hitting is an internal Perl one. So, I need to overcome the Perl limit.
2. I am importing 20M+ records, and need to track the IDs of the records I import. But your point is well taken, and I'll look to see how I might modify how I am importing things.
3. This import is just an intermediary as I am importing into a RDBMS. I'm just trying to import large datasets as quickly as possible.

From your comments on access time, it doesn't sound as though I can greatly speed things with this disk-based approach. This is what I suspected, though I had hoped to find wisdom pointing me to another solution.

Thanks.
