#### Running unit tests

There are two ways to run TensorFlow unit tests.

	ModTime  time.Time
	Modified time.Time

	// Information describing expected zip file content.
	// First, reading the entire content should produce the error ContentErr.
	// Second, if ContentErr==nil, the content should match Content.
	// If content is large, an alternative to setting Content is to set File,
	// which names a file in the testdata/ directory containing the
	// uncompressed expected content.

   * bulkGet(keys)} with a relative large number of keys can cause an excessive number of shared
   * stripes (much like the birthday paradox, where much fewer than anticipated birthdays are needed
   * for a pair of them to match). Please consider carefully the implications of the number of
   * stripes, the intended concurrency level, and the typical number of keys used in a {@code
