* Shall remove the routine at the top of the calling thread's cancelation cleanup stack and
* optionally invoke it (if execute is non-zero).
*
* STEPS:
* 1. Create a thread
* 2. The thread will push 3 cleanup handler routines, then it will call the pop function 3
* times.
* 3. Verify that the cleanup handlers are popped in order.
