On some systems (e.g. Google Fuchsia) the default stack size of new
threads is insufficient, resulting in crashes.

On other systems the default stack size is unnecessarily large,
which can waste a lot of virtual memory.

By setting it to a sufficiently large fixed value we can ensure that
we don't run out of stack space while keeping down memory usage.
