 The attached program should print the regions of the program's stack
 and guard pages using various pthread(3) functions (demonstrated both
 for the main thread and for a pthread it spawns).  This might help you
 to draft the relevant code for Rust.
 
 However, it is not exactly accurate, because the kernel will
 automatically grow the stack of the main thread if its stack usage
 increases, subject to the stack soft rlimit, which the process can
 change itself (subject to the stack hard rlimit, it can't change).
 
 So the results might be stale as soon as you use them.  Which raises
 the question -- what is Rust trying to do with this information and
 why?
