I tried r37205 today, and found it eliminates almost all clicks.

The remainder seem to occur when speed crosses from >1.0 to <1.0, or vica
versa.  Which occurs with some regularity, because my sychronization
algorithm on the clients hunts around a bit for the optimal speed, due to
jitter in the timebases.  But I can still avoid the clicks by setting the
master to play at speed 1.02, so that once in sync, jitter never causes the
client speed to go below 1.0.

So it's good enough, and I am happy.  Thank you Reimar!
