Subject: [PATCH] Wait for Async Tasks during shutdown
|
|
|
|
Server.reload() had this logic to give time for tasks to shutdown,
|
|
however shutdown did not...
|
|
|
|
Adds a 5 second grace period for any async tasks to finish and warns
|
|
if any are still running after that delay just as reload does.
