Ugh. Yes, if the source client behaves like that, then your worst case is 
pretty bad. However, this change only improves the worst case to 1/3 of a 
second (in your example), you certainly don't improve this to 0.

Note that worst case (example: streaming digital silence with a naive source 
client like darkice (and ices in some modes)) is much much worse than this 
even with your proposed modification - possibly several seconds. This can't 
be changed as easily, though. Sensible source behaviour improves this
