Oleg Zaytsev b87c54de14 Load OutOfOrderTimeWindow only once per appender 
We're loading the time window once per each Append() call, plus once in
the Commit(). While not extremely expensive, atomic operations are also
not cheap.

Additionally, it makes sense to keep the window consistent for a single
append.
