I must admit, I haven't really kept up with the coding of this project as=
 much
as I would like to (those AE classes are getting in the way)... is the so=
cket
interface for use on the same machine? If so, then you are correct, it wi=
ll come
at the same time, 1/120 of a second intervals.

If the purpose of the socket is to transmit across a network interface, t=
hen you
are running into latency, bad packet order (requiring reordering and henc=
e more
time), or damaged packages (if using TCP/IP, it will retransmit, if using=
 UDP,
maybe missing a few is okay), all of which add a variable amount of time.

Ideally, you are correct, but if the goal is robustness and use over a ne=
twork,
then packet delivery timing may or may not be consistant.

Sorry if this has no application here, but I thought I might just take a =
stab at
it in case I happen to be right :)
