[En-Nut-Discussion] How much memory is still available in the stack of a thread?

[Harald Kipp]

Each thread has its own stack space, taken from the global heap.

Why do you need to know the available stack space of a single thread? 
Just asking, because I assume that things are more complex than you are 
possibly aware off.
