If the command is not commit/abort etc:

1. Wait for execution in backend 0
2. If okay, execute (paralelly) in the rest of backends (in this case in 
backend 1 and 2)

If the command is not commit/abort etc:

1. Execute (paralelly) in the rest of backends (in this case in backend 1 and 2)
2. If okay, execute in backend 0
