    My recollection is you get an "infinite" stack, demand allocated.
    Exactly the same you get via malloc() - an unpopulated address space,
    which is then populated when you use it.

    Very handy in quite a few situations; no need to predefine your stack
    size (as you would have to without overcommit), no need to mess around
    trapping exceptions (as you do to implement sparse matrixes on
    Win32)...
