Is there a value to this test_fsync test?
Compare open_sync with different sizes:
(This is designed to compare the cost of one large
sync'ed write and two smaller sync'ed writes.)
open_sync 16k write 242.563 ops/sec
2 open_sync 8k writes 752.752 ops/sec
It compares the cost of doing larger vs. two smaller open_sync writes.
