Comment (by olly):

 As of trunk r18193, we're no longer using F_FULLSYNC by default, though it
 can be enabled with {{{Xapian::DB_FULL_SYNC}}} (currently only supported
 by brass).

 Also, brass on trunk only does the full-sync on the final file, and just
 fdatasync() the others, which will probably make quite a difference to the
 slowdown, but we've not yet tested this.
