You can use the browser's "refresh" function instead, don't?  That's
what I'd do, regardless of this problem.

Did you actually see this problem in real life, not with your recipe?

Anyway, I still think you should look at your system's configuration,
since I see nothing similar to this large memory consumption on all
but 1 system where I tried this.  So there are factors here at work
that depend on the system.
