  Sure! I readily accept that in the true multithreaded case
  (multi to multi), all sorts of the usual re-ordering fun
  ensues, but in the case of a single thread signaling to
  sockets in another single thread, strict ordering should
  still be preserved (at least to the same degree that
  ordering is maintained for signals to slots within a
  single thread).

Hmm - in case of queueing, the signals are queued in the identical
(event)queue thus the order cannot get scrambled provided there is only
one 'other' thread as the author expected.
