erts: Tweak over estimation of hashmap size for binary_to_term
Strategy: Calculate an over estimation of heap size that will give
such a low probability for overflow, that "it will not happen".
Scary assumption 1: Uniformly distributed hash values.
Scary assumption 2: Tree size is normally distributed (right?)
