in thread how to tell if a file is still being modified

This is the method we use in batch processing at one of the largest banks in the US. Another method is to poll the size of the file every so many seconds. After the file doesn't grow for N polls (usually 2), we can assume the file is done. -s isn't that expensive, especially in the batch world.
