--- Comment #4 from Fujii Hironori <Hironori.Fujii at sony.com> ---
Produce thread is blocked by enqueueing to m_upperQueue becuase it is full.
https://github.com/WebKit/WebKit/blob/7327aab70ea504499e0f1a14c78f55863233afd9/Tools/TestWebKitAPI/Tests/WTF/SynchronizedFixedQueue.cpp#L86

Main thread is blocked by m_produceCloseSemaphore.wait() because Produce thread doesn't signal.
