:mrdocs:

Return a "reasonable" value for the default thread stack size (in bytes), which, unlike `nativeDefaultThreadStackSize`, is constant across all platforms of a given word size. This value is large enough to guarantee that an automatic array of at least 250 * 1024 pointers may be declared in the top level routine of the thread.
