jumping around in the listview
WOW psuedo-processes always sort directly after their parent

2. User's selected order.
3. PID

Return Value:
< 0 - This CProcInfo is "less" than the other
0 - Equal (Can't happen, since PID is used to sort)

Class Description:
Retrieves the list of process info blocks from the system,
and runs through our array of CProcInfo items. Items which
already exist are updated, and those that do not are added.
At the end, any process which has not been touched by this
itteration of the function are considered to have completed
and are removed from the array.

Provides an API for getting a list of tasks running at the time of the

api is MUCH faster that the non-internal version that uses the registry.
Arguments:

Number of tasks placed into the pTask array.
