Having a sequential list makes iterating through the list *possible*, if 
items are being added at the same time that iteration is happening. I 
have a multi-threaded app here, so several threads are iterating 
through the sequential "unsorted" list, at the same time that other 
threads are attempting to add to the list.

Additions need to be checked for duplicate entries, thus necessitating a 
sorted list for fast lookup.

I suppose I could have specified that list elements won't be changed 
once they are in.

Thanks for the response, though
