      Description

      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.
