> LLAP cache doesn't have defragmentation on branch-2 so it retries when failing to evict.
> There are a couple of issues with retries (e.g. sleep is not applied properly and time
can go negative), also it would be helpful to make use of existing cache dump logic used in
LLAP IO view to dump log state into the log in such cases.
