This is not a great name; at this point task is not scheduled, just merly put in the scheduling queue for scheduling late. Let's keep for now as it at least is in-line with PrioritizedScheduledTask

Yeah I was using taskCreated, but @arhimondr suggested to change to taskScheduled:)

I am not a big fan of readyForScheduling field name. It can flip flop true/false/true/false - and name suggest that when it becomes false the partition is no longer ready for scheduling - which is not true.

No good idea for rename though :P
