Memory usage. Adding a vector to each of the (now over 600000) CBlockIndex entries would be a significant memory usage increase (at least 48 bytes per entry, to be precise, on stdc++ 64-bit platforms). For most operations it's also unnecessary. Inst...

This is some old, but I stumpled over it, so here my two cents: I think "deduplication" is the solution you're looking for. Due to the fact you need to keep each node in its usersapce independent AND at the same time you don't want to prune the node...
