run_recoverable_llvm runs code generation on a disposable thread and terminates
it through pthread_exit when LLVM invokes its fatal error handler. bionic does
not force-unwind C++ frames on pthread_exit, so the lock MCJIT holds over the
execution engine is never released and stays held by a thread that no longer
exists.
Every entry point into the engine takes that lock, so the next compile hangs and
so does teardown. One recovered error, and the emulator is finished until it is
killed -- and the error is recovered, which is the point: it is meant to be
survivable.
Their Kotlin log-channel screen is left out; this port has its own.
