New Revision: 295925
URL: https://svnweb.freebsd.org/changeset/base/295925

Log:
  Following revision r295924, the changes to a db file should be fsynced
  before the file is closed. Consequently, it shouldn't be necessary to
  open the file with O_SYNC any more.
  
  This improves the performance of building large .db files for large
  password files a lot and should resolve this problem:
