The amount of GC I/O on the write buffer is managed by the rate-limiter, which is calculated as a function of the number of available free blocks. When reaching the stable point, we risk having scheduled more I/Os for GC than are allowed on the write buffer. This would result on the GC semaphore balancing the outstanding read GC I/Os to be reported as "hung", though the behavior is normal. Solve this by allowing to schedule when we detect that the read GC path is not moving forward.
