Hi Jeremy,

Thanks for the link. I think that when I would
do this properly, I would have to use a proper
memory pool, which I was just reading about on Boost site.
But since I'm still learning the basics, and I
want to keep it simple, i will preallocate a list,
and use that as a memory pool.
But I will certainly have a look at your code,
and see if I can use it.

Thanks again,

Greetings,

Lieven
