Will Burns commented on ISPN-9722:
----------------------------------

The big thing to watch out for with CallerRunsPolicy is we don't accidentally run operations on the wrong thread is more important, such as running a blocking operation on the CPU thread or CPU operation on the blocking thread pool (although the latter every once in a while wouldn't be that bad).

> Persistence is one of the few remaining systems that are not non blocking. This needs to be remedied. We will eventually need to add an SPI that does this, but for now we need to offload the persistence operations to a different thread pool.
> This should only require changes in the PersistenceManager to return non blocking methods (ie. return CompletionStage). We should then update references to use non blocking when possible.
