    @qihongxu Just as a confirmation, I have used 
https://github.com/jvm-profiling-tools/async-profiler on lock events ie time 
while waiting to enter into a lock and I have found the same exact behaviours 
explained above:
    QueueImpl::checkDepage

    QueueImpl::DepageRunner

    both are calling `PagingStoreImpl::isPaging` and are blocking each others
