First off, fsync() only helps if the system itself
crashes...someone else might want to correct me, but if a process stops
midstream, it should not affect the db in any way, shape or form...

Second, v6.4 was released yesterday...should be available on all
the FTP mirrors by now, as well as the main site :)

No, Vadim was waiting for v6.4 to be released before diving into
it for v6.5 ...
