> Brief steps to reproduce
>  # Enable async scheduling, 5 threads
>  # Submit a lot of jobs trying to exhaust cluster resource
>  # After a while, observed NM allocated resource is more than resource 
> requested by allocated containers
> Looks like the commit phase is not sync handling reserved containers, causing 
> some proposal incorrectly accepted, subsequently resource was deducted 
> multiple times for a container.
