Comment (by martin):

 I have analyzed this, and found the timeout failure to be caused by a test
 design issue rather than a Varnish problem.

 When finishing a fetch, the BO is set to BOS_FINISHED before the fetch
 thread calls VDI_RecycleFd. If the second (esi-included object) fetch is
 issued in this window, it'll create a new backend connection, which the
 varnishtest server can't cope with. This causes a timeout failure.

 One solution could be to alter the test case having the server say
 "Connection: close" on the first reply and do an accept between the
 backend requests.
