Description
The value returned from getrlimit with RLIMIT_STACK includes the guard pages and TLS area, but in pthread_attr_setstacksize the max stack size is MAX_USER_STACK_SIZE. Calling pthread_attr_setstacksize with the value returned from getrlimit thus fails.
According to posix, getrlimit should return the maximum size of the initial thread's stack http://pubs.opengroup.org/onlinepubs/9699919799/functions/getrlimit.html
i.e. USER_MAIN_THREAD_STACK_SIZE (which is the same as MAX_USER_STACK_SIZE).
Patch to follow.

The patch looks OK. Not sure when I get around to apply it. So, if anyone wants to beat me to it...
