The current stampedLock uses a writer-preferred rule, which may lead to extreme
cases where a waiting write lock request blocks the subsequent release thread
from acquiring the read lock, resulting in memory not being released. To solve
this problem, a high priority read lock request interface needs to be
introduced.
