Read and process the file in blocks:
On a related note, I've found the collection of papers below to be helpful in understanding different methods of handling files in Haskell. http://okmij.org/ftp/Computation/Computation.html#enumerator-stream "Now that cursors and enumerators are inter-convertible, an implementor of a collection has a choice: which of the two interfaces to implement natively? We argue that he should offer the enumerator interface as the native one. The paper elaborates that enumerators are superior: in efficiency; in ease of programming; in more predictable resource utilization and avoidance of resource leaks. We present a design of the overall optimal collection traversal interface, which is based on a left-fold-like combinator with premature termination." Greg Buchholz
