Our build was flaking due to ETXTBSY errors running multiple redbean instances in parallel. This is due to the StoreAsset() support which seems to cause enough problems it's worth making a *breaking change* turning it off by default for now. There's a new -* flag, to restore redbean's old self-modifying behavior.
