Another problem with doing this is that you are tying the rate at which file descriptors are closed to the GC profile of your program. If you only have 10's or 100's of file descriptors available it would be very easy to use them all up in a tight loop which did not allocate much memory. It would be a bummer to have your program start failing because you used a more memory efficient algorithm for some calculation. -Eric ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
