I think we need to brainstorm on this.
What are the other ways that we can handle this?
What are the implications , if we put a size limit on the contents file and
when it reaches the max_size, open a second file.
How does other OSes handle this?

Having a huge file is a problem and as time goes, the problem only increases
and performance can only decrease.
So, we must look at this very seriously and search for better alternatives.
