Also, the following line looks pretty useless to me. Unless of course,
there is something that I'm not aware of:

          _S_start_free = static_cast<char*>(::operator
new(__bytes_to_get));
          if (_S_start_free == 0)
//And all the code that follows in braces.

Do you know who was the original author of this pool allocator, because
I need to understand some things, which I doubt that I have understood
properly from the code alone.


Thanks.
