 Specifically:

 >Looking at the way the transient is set in wp-cron.php with microtime()
 it would be almost impossible for the cron to be running concurrently
 without the transient being disabled (which it isn't on our site). It
 would require two requests to fire at exactly the same microsecond
 (different hostname request wouldn't matter as the transient is stored in
 the database). The chances of this happening would be infinitesimally
 small and would not present the quantity of errors we are seeing.
