The RTP reorder buffer code has been pretty much unchanged since... 1.0.2. The 
RTP plugin only buffers when reordering occurs. De-jittering really is done 
downstream in the input clock synchronization code.

There's been quite a bunch of changes to that piece between 1.0.2 and 1.0.3 as 
$(gitk src/input/) shows, but I am not very familiar with it.
