ERROR Error in FileWatcher. Internal buffer overflow

On one installation of Sitecore 8.1 update 2 that I recently did, I noticed lots of errors in the logs like:

5404 15:52:21 ERROR Error in FileWatcher. Internal buffer overflow.

Exception: System.IO.InternalBufferOverflowException

Message: Too many changes at once in directory: D:\inetpub\...\Website\.

As explained here: http://mikael.com/2016/01/sitecore-file-watcher-internal-buffer-overflow-exception/ 

The resolution oddly enough is to move the license file to a subfolder of the data directory.
