This reverts commit b2ee3ad74872bcccaac00b718175f7dcedbd1589.
It makes abnormal behavior on ecore job.
Before adding this patch, ecore job is processed immediately.
But now processing ecore job is delayed.
Hum, could you explain why we want ecore job to not be queued to the next iteration when currently inside a job. It seems it kind of kill any ability to delay a task if it is triggered from inside an ecore job.
