Yes, I recommend to set it to false for now. You are not the first running into issues with this feature, but what you describe seems really bad.

Very deep analysis of this probably isn't worth the effort. The code for this in releases so far was a pretty simple old prototype without careful design, etc. We're close to finishing a much better full rewrite for the /cache/prefetch functionality.
