[Tutor] endless processing through for loop

[Dinesh B Vadhia]

There is no thrashing of disk as I have > 2gb RAM and I'm not keeping the file contents in memory.  One line is read at a time, some simple string processing and then writing out the modified line.

What happens to memory use? Does it start to thrash the disk? Are you
somehow keeping the file contents in memory for all the files you
read?
