double-linked lists

Hi,

I think you answered to the wrong mail :-)

Well, I am not sure how things will look like, if there will be an external 
manager traversing the list or if the listed processes will just take care 
of themselves.

What will happen is that the processes might start sending messages either 
forward or backward in the list.

On second thought, a list will not be enough, but more like a "double-linked 
tree" where one has a 'root' at either end and in the middle there are 
several branches to traverse... Hmmm, this needs more thought! :-)

regards,
Vlad
