/**
* {@link com.hazelcast.map.impl.mapstore.writebehind.StoreWorker} delays processing of

* is used to provide some extra robustness against node disaster scenarios by trying to prevent
* lost of entries in wbq-s. Normally backup nodes don't store entries only remove them from
* wbq-s. Here, we are testing removal of entries occurred or not.
