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
