# Atomic writes to 64bit atomic vars uses compare/exchange to

# guarantee atomic writes of 64bit variables. pg_atomic_write is used

# during initialization of the atomic variable, hat leads to an

# initial read of the old, undefined, memory value. But that's just to

# make sure the swap works correctly.
