Having a fairly quick look through these options, the one I'd be least happy
with would be number 2. We should work towards no possibility of the GUI taking
down the core.
Number 3 superficially looks the least invasive and most interesting. It occurs
to me that the UI can be informed that a graph change has been *completed*
with a 'graph changed' message via the existing ring buffer used for all other
GUI updates. That ring buffer is non-blocking so if the GUI goes away the ring
buffer will fill, and further messages are just thrown away.
If all is well, the GUI would then request the data for updating its local
copy. We need to keep in mind that request can be quite late as the GUI has a
refresh rate of at least 33mS. It can be slower if there is a lot of GUI
activity.
Finally, a reminder that per instance there can be two EQ graphs visible at any
time. System effect or Insert effect, and Part effect.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
