If some checks exceeds the reporting period, we end up overrunning
intermediate buffers.

reactor.core.Exceptions$OverflowException: Could not emit tick 6784 due to lack
of requests (interval doesn't support small downstream requests that replenish
slower than the ticks)

It looks safe to consider a check exceeding the reporting period
as failed, thus preventing the buffer overrun.
