That's actually a very good suggestion. First I figured that in this way
files changed within the hour after creation would be ignored, but they
probably represent a very small minority anyway.
On the other hand, this does not really rectify the situation, but will
allow us to postpone the real sync again until, let's say a holiday, where
we have plenty of time to sync.

In your situation you might want to use --modify-window=3600
and each night either reduce the window or apply it to fewer
files.  That way you can spread the load.

You'll need to do this again in April 8-(

Holloween came early for you.
