I am having difficulty understanding the logic behind:

*/5 * * * * php absolute_path_to_civimail.cronjob.php
( Found at: http://en.flossmanuals.net/CiviCRM/SystemConfiguration )

In my mind, I see that ending up running MANY instances of civimail.cronjob.php at the same time, turning into a complex nightmare.

Or is civimail.cronjob.php coded that it will not run longer than 5 mins? or or or?

Please help me understand the logic behind this... once understood I will activate the cron job on our server.

Otherwise, the cronjob has a lock, to prevent loads of crons running together.

Aaaahhh, that makes MUCH MORE SENSE! Thank you, xavier!!!

Might should clarify in the docs that bunches of cron tasks are not all going to be fighting at once for resources, mutex semaphore, bla bla bla... I do not know what all protection is in place, so someone more knowledgeable than I please!
