A bold statement, but I kind of agree. Except maybe for when you seek to simulate many random, unpredictable, asynchronous processes, threads are just a quick hack. A hand-crafted, event-based solution is usually more efficient, easier to get right and much easier to debug.
If you lack the needed OS primitives (select, non-blocking I/O, etc.) or if you need to cope with a bad OS, then threads might be the only way to go, but those are cases that call for ugly hacks anyway.
What is it you couldn't do in the raw-sockets egg without threads? Tobia
