cooperative versus preempt

it would seem a few major issues about this are being ignored:

1.  wouldn't it be easier to exploit multiple processor architectures and 
distributed computing under preemptive threading? is tunes a single 
processor OS, end of story?

2. as more and more OS's use threading, the hardware people will come 
around and implement threading in the processor.  state changes and 
object protection won't take any noticable time at all.  it happened with 
floating point and memory management, its only a matter of time for 
threading. (and hopefully garbage collection)

3.  who really cares if a percentage of time is spent dealing with 
threading?  as someone posted earlier, one can just wait a year and 
processors will double in speed.

4. real time computing requires preemptive scheduling.
