I have a program running on multiple machines with NFS and I'd like to log all their outputs into a single file. Can I just run ./my_program >> filename on every machine or is there an issue with concurrency I should be aware of? Since I'm only appending, I don't think there would be a problem, but I'm just trying to make sure.

sys.stdout not reassigning to sys.__stdout__

I'm pretty new to Python so I am still just learning the language. One of the things I came across was reassigning sys.stdout to change the default output of print.
