----------------------------------
Hi [~stack]
I Just provide a patch, after review the AM code, I think the order only
matters in bulk assign of regions which happens when master start and server
crash. I modify some code, so that AssignProcedure of system regions will be
submitted before user regions, and in that way ProcedureExecutor will assign
the system regions first. Let me know if I misunderstand something, or need to
consider more. Thanks
