Subject: [PATCH] Async command map building
|
|
|
|
This adds a custom pool inorder to make sure that they are closed
|
|
without much though, as it doesn't matter if the client is not sent
|
|
commands if the server is restarting. Using the default async pool caused issues to arise
|
|
due to the shutdown logic generally being much later.
