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 :)
