pre-5.0.33 value to have some margin for future changes in compiler, glibc,

As of 5.0.45 and F9, it seems 16384 isn't enough anymore (ppc fails).
But we can't raise it too much because it has to be less than
DEFAULT_THREAD_STACK / 8, and DEFAULT_THREAD_STACK is dependent on
SIZEOF_CHARP. (Could change DEFAULT_THREAD_STACK too if our backs are
to the wall, but I'd rather not.)

Feel free to raise this by the smallest amount you can to get the
