Hello! Is this::field.isInitialized considered thread-safe? (field is a lateinit var). Trying to figure out if I need to make sure the field gets created from the same thread that it's later accessed from, or if I can just rely on isInitialized being thread-safe 😄

no, and even if it were, you'd have a TOCTTOU race

[czuckie]

wait, would you have a TOCTOU? You can't go from initialised to uninitialised can you?

[czuckie]

oh, but you can go from uninitialised to initialised doh
