--- Comment #1 from Fujii Hironori <Hironori.Fujii at sony.com> ---
_exit() is called on the IPC thread. However, Bug 210955 fixed
only the case of exiting program from the main thread.

There can be some solutions:

1. Call _exit() on the main thread
2. Return from the main function
3. Use TerminateProcess API instead of _exit() (Bug 210955 Comment 3)
4. Skip the destruction of ~ThreadHolder in the thread invoking _exit() by adding a flag
