replace if key is different, or depth is higher: no mesurable impact (tiny gain?)
2 slot tt clusters, replace the one with the lowest depth: small regression.

Tried a couple more, which didn't work, based on 2 slot clusters:

replace least valuable entry, where value = depth + 2*age
ditto with value = depth + 2*age + (bound==EXACT)

Same with 1 entry per cluster. Also failed (hard).
