I think the comments are accurate in this case:

 * Set cache-bypass threshold.  Files larger than this size will not be cached.
 * With a threshold of 0, the cache is always bypassed.  With a threshold of -1,
 * cache bypass is disabled.

cache bypass is relatively new (in terms of stuff that's built by
default), which is why there's little to no docs on it.
