Charm++ parallel programming system

From my experimentation it appears that if you call AtSync() before the LBPeriod has elapsed, the application will block until the next load balancing period occurs.  So, if you start an application with an LBPeriod of 0.5 seconds and call AtSync() at 0.25 seconds, it will then block for the period from 0.25 to 0.5 seconds, invoke the load balancer at 0.5 seconds, and then return control to the application.

Is this a correct understanding of how AtSync and LBPeriod are related?
