Comment (by bdash):

 This is because OS X's version of SQLite has checkpoint_fullfsync enabled
 by default. This causes SQLite to use the incredibly heavyweight fcntl
 F_FULLFSYNC that blocks until all buffered data is flushed to the disk
 platters. This is in contrast to on other platforms where SQLite simply
 uses fsync, which blocks until buffered data has been flushed from host
 memory to the disk controller.
