kosaki: any ideas for the lack of guard page for the main thread?

I have one idea, but I hate it: run timer thread function in the main
thread and have all normal Ruby code in pthread_create-ed threads.

However, long term, I will try to remove the timer thread and GVL
w/o slowing single-thread case.
