It's easy to turn off:

    remove_action('init', 'wp_cron');

Then just set up your own real cron job to run the `wp-cron.php` script however often you'd like.

> If your site gets a large influx in traffic the server runs wp-cron for every page hit and further slows things down.

Which involves a single database hit and a `foreach` loop. Or, if you're using an external object cache (memcached, APC, etc), no DB hits.

Probably not as dire a situation as it seems. This...

...is a huge problem.

Why?

If you are relying on things to happen at an exact time, them you should know not to use wp-cron. However, for the scope of internal wordpress tasks that don't need to happen every load, I don't see any problem with it happening when wordpress is prodded eventually, and the time it was scheduled to run at has passed.
