I think that the performance problems are likely to be related to the 
number of conversations in your list. I use an ArrayList as the primary 
structure, but there are a number of places where I iterate over the 
whole list, I think.

It works in the main use cases, and in particular, *my* main use cases, 
so if anyone is keen to investigate better in-memory data structures and 
algorithms, I'd be happy to take patches :-)
