-/* There is an obscure bug in the kernel due to which RLIMIT_STACK is sometimes
-   returned as unlimited when it is not, which may cause this test to fail.
-   There is also the other case where RLIMIT_STACK is intentionally set as
-   unlimited or very high, which may result in a vma that is too large and again
-   results in a test case failure.  To avoid these problems, we cap the stack
-   size to one less than 8M.  See the following mailing list threads for more
-   information about this problem:
