Don't buffer up tables in memory on compaction. (#6422) 
We can instead write it as we go, and then go back and write in the
length at the end.

Also fix the compaction benchmark, which indicates no changes.

For the benchmark, this brings maximum memory usage of the buffers 
from ~200kB down to 128B.
