> Placing WAL records into files in work directory (preallocated size; files with same name) was intitially done for perfomance reasons.
> But for case there is no activity in the system there is no need to keep open segment in work directory. 
> It is possible move data of this incomplete segment into archive.
> Proposed change: wait some configurable time, e.g N minutes and move WAL segment to archive.
> This operation should be done with appropriate lock held to avoid writting record to WAL segment which is being archived.
