* - System.nanoTime() is expensive enough that we want to call it the minimum required number of
   *   times, typically once before invoking a blocking method. This often requires keeping track of
   *   the first time in a method that nanoTime() has been invoked, for which the special value 0L
   *   is reserved to mean "uninitialized". If timeout is non-positive, then nanoTime need never be
   *   called.

### Tips for code changes
Following these tips prior to raising a pull request will speed up the review
cycle.

* Add appropriate unit tests (details on writing tests can be found in the
  [TESTING](TESTING.asciidoc) file)
* Add integration tests, if applicable
* Make sure the code you add follows the [formatting guidelines](#java-language-formatting-guidelines)

// permanent deletes (by specifying a version ID in the delete operation) have three states "Pending", "Complete"
