Does this implementation also need to do delayed updates to the stripe
cache? I.e. we bypass the cache and get the requester the data it
needs but then schedule that data to also be copied into the cache by
the work queue. The thinking being to reduce the read penalties
associated with subsequent writes to the stripe.
