Subject: [PATCH] Make CallbackExecutor strict again
|
|
|
|
The correct fix for double scheduling is to avoid it. The reason
|
|
this class is used is because double scheduling causes issues
|
|
elsewhere, and it acts as an explicit detector of what double
|
|
schedules. Effectively, use the callback executor as a tool of
|
|
finding issues rather than hiding these issues.
