Drop unneeded desync patch
spigot no longer even fires the event for this case, so, this may
actually be a regression, not too sure here, but, as-is this patch
is dead

Subject: [PATCH] Do not overload I/O threads with chunk data while flush
saving
If the chunk count is high, then the memory used by the
chunks adds up and could cause problems. By flushing
every so many chunks, the server will not become
stressed for memory. It will also not increase the total
time to save, as flush saving performs a full flush at
the end anyways.
