Cloudflare timeouts (err. 524) adding content

With CKeditor module active on sites proxied by CloudFlare, you can suffer annoyingly HTTP 524 error timeouts (when your server reaches above 100 secs to send response) very frecuently. I've found that it happens because the ckeditor.xss process doesn't return control to the add node main process in accurately time.
You can bypass this switching to "plain text editor" after you added the content and just before sending the post.
I would like to give a code solution, but my php skills are not enough.
I open this issue in order to give a bypass for those that encounter this problem and, hoppingly, more skilled developer could find a solution.
