Description

We should synchronize the counters in all tasks after a sync() call.

Then someone can use it for flow control. E.G. graph related algorithms, to get the number of globally updated vertices.

Two options to solve this:

• Sync the whole stuff over RPC from the BSPMaster
• Use Zookeeper for counter handling
