should be a value past to pthread_attr_setguardsize, not a rounded up value. Also fix a stack size matching bug in thr_stack.c, now stack matching code uses number of pages but not bytes length to match stack size, so for example, size 512 bytes and size 513 bytes should both match 1 page stack size.
