Looking at the code, _SignalReactorMixin.mainLoop() takes the output of
ReactorBase.timeout() and passes it to doIteration(). The
implementation
of doIteration() in PollReactor passes the value straight through to
poll(). If there is any kind of timed call pending (which there is),
the
timeout value counts down. Eventually it gets very close to zero. If
there is a burst of AMP activity around that time, there's a good
chance
that the one of the poll() calls will time out.
How this leads to the data being lost is another question, but the
coincidence of events is too much to ignore.
This is entirely normal. It's how timed calls are implemented in almost
all of the reactors and it's how they've been implemented for at least
13 years. :)
It's possible there's a bug here but this sequence of poll() calls with
these timeout values doesn't surprise me at all.
