Threading systems have come a long way in the last decade or so,
and they're still advancing. 64-bit, multi-core processors make
mega-threading even more attractive.

To read why zillions of threads are good, see:

For an example of a high-performance server that uses massive
threading, I'd nominate MySQL.

Prediction: Ten years from now, someone will ask that same
"What possible use..." question, except the number of threads
will be a million.
