Why don't you send the message to the previous agents in the cell?
Having all agents say "you guys listen to me now" is not a reliable
approach if you don't know what agent will arrive last.

You mean "static" and "synchronized" in the Java sense?  Hmm, my
impression is that you need to think harder about the schedule
activateIn patterns and not try to keep order among agents of a class
using a class-wide data structure.  Also, Java-synchronized methods
won't have any special meaning in Swarm since every Action now is issued
in sequence, and never in parallel.
