We cannot put blocking network I/O onto the worldgen threads, this will crash the server if it stalls

Subject: [PATCH] Fix chunks refusing to unload at low TPS
|
|
|
|
The full chunk future is appended to the chunk save future, but
|
|
when moving to unloaded ticket level it is not being completed with
|
|
the empty chunk access, so the chunk save must wait for the full
|
|
chunk future to complete. We can simply schedule to the immediate
|
|
executor to get this effect, rather than the main mailbox.
