--- Comment #1 from netterfield at astro.utoronto.ca ---
Unfortunately, this is not how kst realtime works - it only works with growing
files.  If instead of deleting the oldest line, you just leave it and let the
file grow, it will work fine, at the expense of a small amount of disk usage.

One could, in principle, put in a timer based reload, but without also
implementing some sort of file locking strategy, this would lead to race
conditions or partial reads, so I am hesitant to implement it.

Is there a reason why you can't keep the old data and let the file grow?
