OK. It seems that a prominant companies field rep has read some of the
linux FUD and believed it:

> My limited understanding of Linux is:
>
> A. The kernel doesn't implement kernel-mode threads.
> B. With Linux, the scheduler can't preempt the kernel, which is
> needed for the scheduler to divide CPU time among the threads.
> C. Lastly, with Linux, the kernel is not reentrant. In other
> words, no matter how many processors are in a system, only one processor
> can execute code at a time.

I know that these are certainly not true for 2.2.X. I seem to remember
that there was a nice rebuttal of these points posted somewhere, anyone
remember where?
