//
// Define levels for locks used by the replicator service.  These levels
// are checked during debugging.  Locks which shouldn't be held at the same
// time can have the same level.  Make sure there are no conflicts with the
// reserved lock level(s) in netlock.h.
//
// Config data lock can be held while getting client list lock.
// For instance, this happens in NetrImportDirAdd.
//
// Config data lock is held while getting a master list lock in
// NetrReplImportDirAdd, GuardUpdate, etc.
//
// Client list lock can be held while getting lock on delay list.
// This happens when ReplDoUpdate calls ReplScanQueuesForMoreRecentMsg.
//
// The client list lock can be held while getting a pool lock.  This
// happens when ReplRemoveClientRecForDirName calls ReplClientFreePoolEntry.
// Also ReplCheckTimeList calls ReplQuePut, which calls ReplClientGetPoolEntry.
//
// Client list lock can be held while getting lock on work queue.
//
// Client list lock can be held while getting lock on duplicate list.
//
// The delay list lock can be held while getting a lock
// for the work queue.
