With the addition of journalled soft updates, the "newblk" structures

Browse Source 
persist much longer than previously. Historically we had at most 100
entries; now the count may reach a million. With the increased count

newblk hash table. Configure the newblk hash table to accurately reflect
the number of entries that it must index.
