Remove bad server.scheduleOnMain disconnect calls from old patches
The new behavior of disconnect to block the current thread until the disconnect succeeded is better than throwing it off to happen at some point

Subject: [PATCH] Make sure inlined getChunkAt has inlined logic for loaded
chunks
Tux did some profiling some time ago and showed that the
previous getChunkAt method which had inlined logic for loaded
chunks did get inlined, but the standard CPS.getChunkAt
method was not inlined.
