An object can be cached as "not cacheable".
When we have a cache-miss, the client goes to the backend. If another
client asks for the same object before that first client has got a
response from the backend, it is put on hold.
If the response was not cacheable, we insert a "not cacheable" object,
so that clients that ask for this object go to vcl_hit and hit the
backend right away, even if other clients are already hitting the
backend for that object.

Never attribute to malice what can adequately be explained by incompetence.
