Comment (by phk):

 Normally we don't hold more than one worker thread "hostage" while we wait
 for the backend to reply, but in this case references via ESI:include will
 hold their worker thread hostage also.

 Depending how often ESI:include hits busy objects, this may or may not
 lead to increased thread pools.

 Using grace, even with just a couple of seconds grace, would mitigate this
 in many cases.

 Dunno about 2.0.2, that's not my decision.
