Threads have been part of Java since Day 1.  Using threads complicates
your code, but even with a single core processor, they can improve
performance, particularly if you are doing something like combing
multiple websites.

The nice thing about Java is whether you are on a single core
processor or a 256 CPU machine (We got to run our Athena Integer Java
spreadsheet engine on such a beast), does not concern your code.

You just have to make sure your threads don't interfere with each
other, and Java/the OS, handle exploiting all the CPUs available.
