This is needed for n2n mapped files and for forwarding-mode
proxies.
Access stats are still collected on per file basis. If several IOs all
read from the same file at overlapping times, these will all be
reported as a single access. This can be improved if needed.
When a block fetch fails on certain IO, other IOs will reissue the
block request. The offending IO will get the error code result
associated with its request. When prefetching, the bad IO will be
removed from the prefetch IO map so it doesn't cause trouble again.
