Thanks.  I was about to tell that I couldn't reproduce the problem on
a machine where I have OneDrive set up.

Would you mind please telling more about the situation where it
happens and about the symptoms?  Does this happen only with
find-file-literally? does it happen only with large files? and what
exactly are "metered connections" and how does one disable that
option?

The reason for the questions is that I'd like to describe the problem
and the solution in etc/PROBLEMS.

Thanks.
