The 8.3 bgwriter keeps running even during checkpoints, so it's feasible

I wonder though whether the walwriter wouldn't be a better place for it.
I do, too, but that wasn't available until too late in the 8.3 cycle to
consider adding this feature to there either.
There's a couple of potential to-do list ideas that build on the changes
in this area in 8.3:
-Aggressively pre-allocate WAL segments
-Space out checkpoint fsync requests in addition to disk writes
-Consider re-inserting a smarter bgwriter all-scan that writes sorted by
usage count during idle periods
