[development] Batch API on cron

[Yves Chedemois]

Batch API works around the PHP timeout limitation by relying on a client 
browser to iterate separate requests, each of which stays below the time 
limitation.
So yes, Batch API can only be used in a UI context, which excludes cron.

For the same reason, it is not recommended to fire a batch processing 
inside an API function, since you cannot ensure it will be executed in a 
safe-for-batch context.
