OK, I'll commit this with the following comment to the description of
MAX_STACK_SIZE.:

+/* 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:
+   <http://sourceware.org/ml/libc-alpha/2012-06/msg00599.html>
+   <http://sourceware.org/ml/libc-alpha/2012-06/msg00713.html>.  */

This test case is now about 1/3 comments :)
