from the POD:
memory - This is an upper limit on the amount of memory that Tie::File will consume at any time while managing the file. This is used for two things: managing the read cache and managing the deferred write buffer

I didn't find that misleading. It says to me that only chunks of the file data are loaded into memory. In fact, I assumed that it loaded a full index of the lines at instantiation.

If the OP knows about how much data an average (or the largest) backtrack is, the read cache could optimized for memory usage/speed. Plus you get a layer of abstraction to hide any nastiness.
