> We need to ensure that all points at which we persist data are protected by (optional) fsync.
> At the time of this writing, we do not fsync on directory creation for blocks. We also do not fsync consistently when doing a remote bootstrap.
> Doing this in an optimal fashion requires an API that allows for control over fsync on blocks and block directories in batch fashion for remote bootstrap and in small batches or single files / directories for regular flushes.
