Be careful: the "-s" option just changes the _initial_ thread's stack.

The stack size for subsequent threads is hard-coded into libpthread,
in uclibc.  You can override it with pthread_attr_init,
pthread_attr_setstacksize, and modifying all calls to pthread_create.
Unfortunately no global run-time setting.
