I'm testing the new asynch commit feature on various raid
configurations and my early findings is that it reduces the impact of
keeping wal and data on the same volume.  I have 10 disks to play
with, and am finding that it's faster to do a 10 drive raid 10 rather
than 8 drive raid 10 + two drive wal.

anybody curious about the results, feel free to drop a line.  I think
this will be a popular feature.
