> When two nodes join a cache in quick sequence, it's possible for a {{CacheTopologyControlCommand}} to arrive between {{LocalTopologyManagerImpl}} adding the {{LocalCacheStatus}} to the {{runningCaches}} map, but before it calling {{cacheStatus.getTopologyUpdatesExecutor().executeAsync(() -> joinFuture)}} to block topology updates.
> This exposes a bug in the way {{LimitedExecutor}} wraps a {{WithinThreadExecutor}}, which causes {{SyncPrepareUseSynchronizationTotalOrderTest}} (and possibly other total order tests) to hang:
