Of course NT is a real multi-tasking OS! Within a single parent process you
can have any number of threads, all running indpendently from each other.
They inherit a resource pool from the parent. So Oracle/NT is a single
process with separate threads running at different priorities. This concept
of a parent process with child threads has been used successfully in other
multi-tasking OS's, especially real-time, pre-emptive multi-tasking OS's.
Whereas UNIX lets you spawn a child thread that can outlive its parent,
this is doesn't happen in other OS's.
