Avoid using Pickle::WriteSize(), which writes an architecture-dependent amount

Avoid using Pickle::WriteSize(), which writes an architecture-dependent amount

Uses that never persist or send pickles over the network are [probably] safe,
but having the method around is waiting for accidental misuses.)
