Bryan,

Thanks, I was thinking the same, may be get all the root level processors and 
filter them instead of going through each processor group(one call to each PG 
will be expensive).

You could probably achieve the same thing but traversing the process groups and 
asking each one for its processors without the includeDescendantGroups=true.

It would be more complex on the client side, but would avoid making one huge 
request.
