  We reconsider post-inflation gravitino production, in the context of hidden
sector supergravity models. We discuss the possible role of supersymmetry
breaking from finite temperature effects in enhancing the rate for gravitino
production and argue that there is no such enhancement. Our conclusion is based
on a simple decoupling argument, which is independent of temperature. We also
characterize the properties of goldstino-like hydrodynamic fluctuations that
arise in supersymmetric models at finite temperature. We show that they cannot
lead to enhanced gravitino emission via infrared divergences. We comment on an
analogy with axion emission from hadronic matter.
