So you don't even try to argue about database-servers-like applications? Apache maybe indeed not very good example because of good degree of independence between threads, though I think in some cases caching across different connections and thus across different threads could be useful.
> The danger with threading is in concurrent access to data. I understand that. That's why concurrent access should be made very wisely. But if this concurrent access is to some cache which allows to avoid huge amount of disk reads - it's worth the effort. And my overall point here is that there's no universal taboo "threads are evil in all cases". It totally depends on the type of application.
