I'm certainly not wedded to pgbench, give it a try.
BTW, I forgot to mention that it would be useful to try different
wal_sync_methods along with this. The reason why it seems unlikely
the patch is useful on Linux is that the sync methods that use O_DIRECT
probably dominate using the patch anyway. There may or may not be
a similar dependence on sync method on other kernels ...
