Hmm, seems like you've managed to hit an infinite loop in LLVM :-(
That explains why it's not responding to SIGTERM - LLVM would not
know that it's supposed to check for interrupts every so often.
I'm afraid you'll have to go the immediate-shutdown route (and it'll
still take a few seconds).
Going forward, you should try to update to newest LLVM. Or disable JIT.
