While starting up a node (commit 6fc6325), it was apparently taking curiously long to load the ban list. RPC (in warmup mode) kept returning `Loading banlist...`. When I checked the log I happened upon the following:

```

```

I think it's a matter of the init message not being updated for a new initialization phase after loading the banlist.

            nBytesToPrune = vinfoBlockFile[fileNumber].nSize + vinfoBlockFile[fileNumber].nUndoSize;
            if (vinfoBlockFile[fileNumber].nSize == 0)
                continue;
            if (nCurrentUsage + nBuffer < nPruneTarget)  
                break;
            
            if (vinfoBlockFile[fileNumber].nHeightLast > nLastBlockWeCanPrune)
                continue;
            PruneOneBlockFile(fileNumber);
            
            setFilesToPrune.insert(fileNumber);
            nCurrentUsage -= nBytesToPrune;
            count++;
        }
    }

    return true;
