Topic: does CSV.read allow another process to keep writing to file?

I'm running a pretty expensive job on a cluster. This generates plaintext output files by appending new lines with data regularly (roughly once every second or so).

I've written some julia code to perform quick visualizations (also on the cluster!). But before accidentally messing anything up I want to double-check:

Is there any chance that CSV.read("filename.dat", DataFrame) could interfere with the other process writing to these files?
The CSV docs on input use a lot of words that I'm unfamiliar with.
