Don't actually do anything, just force a frame object to be created.

Yo dawg, I heard you like frames, so I'm allocating a frame while
you're allocating a frame, so you can have a frame while you have a
frame!

Stash a reference to the entire stack for walking later.
It may look crazy, but you'd be surprised how common this is
when using a test runner (like pytest). The typical recipe is:
ResourceWarning + -Werror + a custom sys.unraisablehook.

A separate thread isn't needed to make this code crash, but it does
make crashes more consistent, since it means sneaky_frame_object is
backed by freed memory after the thread completes!
