But isn't this something every current PITR archive already "works
around"... Everybody doing PITR archives already know the importance of
making the *appearance* of the WAL filename in the archive atomic.
Don't docs warn about plain cp not being atomic and allowing "short"
files to appear in the archive...
I'm not sure why "streaming recovery" suddenly changes the requirements...
