The context switching problem is becoming a thing of the past,
especially on x86 machines with HyperThreading and double cores, where
you have two or even three different pipelines for processing
instructions, making 'context switching' a matter of latencies at the
micro-programming level. These processors became mainstream last year
and prices have been steadily dropping ever since.
Linux Kernel support for this feature is just a matter of carefully
building a HT-enabled SMP version. And Microsoft Windows support, while
much more lackey than the Linux one, as usual, is acceptable.
Before anybody objects that x86 + ( Linux || Windows) is not something
universal should remember which processor Apple is retooling its
production lines for :)
Miguel.
