----------------------------------
Resolution: Fixed
> Add a way to synchronize full GC calls across workers

>
> In applications which use memory more heavily, we can see full GC pauses
> happening on different workers at different times, and each of these is
> causing some delay because other workers are often waiting on something from
> the worker in GC (closing open requests, finishing superstep, etc). Having a
> way to coordinate when full GCs are called could help them have less effect
> on job performance.
