Follow up from #68, this will allow us to simplify the code greatly:
_queue_write" becomes a simple inline call to "
set_deflate" can be handled outside protocol: just setting the new value asynchronously, removing lots of cruft from protocol written specifically for dealing with threading
self._decompressor.decompress" from the main read thread loop (do it per packet only)
done in r1166
We cannot drop all of it from the read loop though because old clients still send the initial packet in the old format. This can be removed at a later date.
