Review Comment:
We're changing the append operation from a fast-append to a regular append
when it hits a threshold. I would be more comfortable with keeping the
compaction separate. This way we know that an append/overwrite is always fast
and in constant time. For example, if you have a process that appends data, you
know how fast it will run (actually it is a function of the number of
manifests).
