      * Fix a SEGFAULT by ensuring that buckets that may have been buffered in the · 91104c75
      Ruediger Pluem authored 
        network filters get flushed to the network. This is needed since
  these buckets have been created with the bucket allocator of the
  backend connection. This allocator either gets destroyed if
  conn->close is set or the worker address is not reusable which
  causes the connection to the backend to be closed or it will be used
  again by another frontend connection that wants to recycle the
  backend connection.
  In this case we could run into nasty race conditions (e.g. if the
  next user of the backend connection destroys the allocator before we
  sent the buckets to the network).

  Remark 1: Doing a setaside does not help here as the buckets remain
  created by the wrong allocator in this case.

  Remark 2: Yes, this creates a possible performance penalty in the case
  of pipelined requests as we may send only a small amount of data over
  the wire.
