How to avoid emails from wp-cron.php when using preload?

Hi, your plugin is great and in my experience it is definitevely faster than Supercache (that I used before) 🙂

I have only a problem…

I use the Preload function.
I have set the linux cronjob option to email me, in case of errors.

The problem is that I receive a lot of emails with this text:
<strong style="color:lightgreen;">OK</strong> http://www.mysite.com (desktop)<br><strong style="color:lightgreen;">OK</strong> http://www.mysite.com/page2 (desktop)<br><strong style="color:lightgreen;">OK</strong> http://www.mysite.com/page3 (desktop)<br><strong style="color:lightgreen;">OK</strong> http://www.mysite.com/page4 (desktop)<br><br>4 page have been cached<br><br>

(that i didn’t receive before with Supercache, nor now from other plugins that use wp-cron)

Please may you patch or add an option to avoid emailing from preload function in cronjob?
Thank you.
