Galène is fairly well optimised, on a machine with hardware crypto, most
of the time is spent in the write system call.  I'll post a profile when
I'm next at the lab.

I can drop every second frame without causing video corruption, and I can
put backpressure on the sender, the code is already there.  The only
difficulty is how to determine that I'm under load.
