I'm wondering what the better way is. :)

Rather than storing the whole file in memory, use a 2 pass solution. In the first pass, gather the locking information. In the second pass, remove the appropriate lines. Each pass will consist of just a while loop that only holds one line at a time in memory.

Update: Another option would be to use Tie::File. It lets you treat the file as if it were an array but manages all of the gory details for you. I just looked at the man page and it has an option to limit the amount of memory it consumes.
