prefetching should apply to 1MB reads
We should allow prefetching up to and including the value of zfetch_array_rd_sz (default 1MB), as was the case before the fix for 5987 was integrated.
Workaround: Increase the zfetch_array_rd_sz so that's it's greater than 1MB:
echo "zfetch_array_rd_sz/W 0t1048577" | mdb -kw
