Hmmm...not what this says...they claim a hard fault is asking for
virtual memory (i.e. swap).

Any hard faults means you're using swap space.
Mike,
that's incorrect information, the most common cause of hard page
faults is where a process requires more memory. A hard page fault is
a request for a page of memory that is not already mapped to physical
memory.

Mike,
I should be clear that real new memory in a process working set is a
demand-zero fault which is classed as a soft page fault in Windows.
