   The white space cleanup patch looked good, so I applied it.  Allowing
conflicting RIDs and flushing appropriately seems like where we need to
go.  It's not unreasonable that someone would want to create lots of
domains on a large ia64 box.  I don't currently have a setup to test
this many domains either.  Thanks,
