Description

Filesystem chain is a per-class decision. Either fsyncs are passed thru to the hardware or not globally for the test. If you have a really slow test, this can cause occasional unbearably slow runs when it gets unlucky.

  /**
   * Annotation for test classes that should avoid always omit
   * actual fsync calls from reaching the filesystem.
   * <p>
   * This can be useful, e.g. if they make many lucene commits.
