Summary: Assume a coroutine that is waiting a synchronize monitor was scheduled to a carrier thread, and the carrier thread is doing as a poller. If the poller is trying to get this synchronize monitor at this moment, and then the poller will park because can not acquire the monitor. This case will cause a deadlock.
