Implemented full buffer-sharing everywhere it could feasibly be done.
The performance and scalability gains are nothing short of stunning,
A full project now uses almost literally zero CPU at idle, all without
resorting to any kind of sleep state hack to stop processing.  All tracks
are ready to make some noise at all times, but do nearly no processing
when they aren't...

This is only possible because the the plugin system has been closed off
and integrated directly into PyDAW, this wouldn't be workable with
3rd party plugins...
