Thanks for PR.

It seems OK, but it's hard to check because there are many lines. Please create few PRs. wp-cache-phase2.php has a lot of lines and it's impossible to check entire file in one step. I just created one example which could be easier to check and merge - #495. We could wait merging #495, then submit next PR,... I think that's better approach. Also, it's easier to fix conflicts with other PRs. What you think?

Going to close this to defer to #754 since the OP has closed their GH account.
