Zach Brown 64b19558b6 Remove last bit of chunk exists region file fix
CraftBukkit removed their implementation that caused this issue,
switching to Mojang's implementation which doesn't appear to share it. I
already removed the important bit in the last upstream merge, this is
just unused and unnecessary now. So we remove it.

Subject: [PATCH] Remove CraftScheduler Async Task Debugger
I have not once ever seen this system help debug a crash.
One report of a suspected memory leak with the system.
This adds additional overhead to asynchronous task dispatching
