I am thinking we might simply have a bug in core/semaphore.cc. Based on these two lines:
semaphore::trywait (this=0xffffa000012d4680, units=units@entry=1) at core/semaphore.cc:64 -> from VM Thread and semaphore::wait (this=0xffffa00001f95680, units=units@entry=1, tmr=tmr@entry=0x0) at core/semaphore.cc:46 -> from Signal Dispatch it seems that VM Thread is waiting on mutex _mtx while the Signal Dispatch is waiting on the timer to expire or be interrupted (?) which never happens (why?). But what is weirder is that Signal Dispatch seems to be indefinitely stuck waiting for the mutex to be released. Is it because the core around waiting does not release the mutex? *This* address seems to be different for each thread so these seem to be different semaphores, right? But then I do not see other threads having stack traces that involve semaphore code. What am I missing? Which thread is holding the mutex VM Thread is waiting for in try_wait()?
