Ignoring fsync/O_SYNC means that the file system driver doesn't flush
its write buffers when instructed to do so. Maybe the data gets written.
Maybe not. You can't be sure of it unless writes are atomic, and you
don't get that from MooseFS.

So, like I said, good luck with that. Because outages like the one that
clobbered Cambridge back in November 2012 happen.
