> Currently a closure from {{runConsistently}} does not consider internal needs of an engine. For example, in {{aipersist}} checkpointer may already wait for {{writeLock}} acquisition, while "we" continue doing some work in our closure, stalling the entire system.
> We should provide an additional API to give users an option to stop the execution preemptively in case if engine needs resources, something like this:
> {code:java}
> interface Locker {
>     ...
>     boolean shouldRelease();
>     ...
> } {code}
> I suggest not renaming the {{Locker}} class itself, that would bring too many unnecessary changes.
