Javadoc
Executes a task from the taskFactory for each of the given partitions.
The reason this method exists is to prevent a bubble of operations/tasks
to be created on the work-queue if the regular
#execute(Operation)would be called in a loop.
The consequence of this bubble is that no other operations can interleave
and this can lead to very bad latency for the other operations.
This method can be used to create Operations and Runnable's to be executed
on a partition thread.
No check is done if the partition is actually local or not!
