# Monitor counts are unstable in the face of concurrency, since different
# clients may get different upstreams assigned for their operations. This might
# also change later when tiered load balancing is available.
# Another constraint is that some global counts are updated by the statistics
# collection task scheduled to run every second.
#
# This test assumes current round-robin policy:
# - default backend is rotated every time we successfully pick an upstream
# - upstream connections within the same backend are rotated in the same way
# - the monitor entry order for upstream connections reflects the connection
#   order within its CIRCLEQ_
