|
|
* function if we don't. The system is rather more complicated than it needs
|
|
* to be, since we only ever use it to destroy windows which are asked to
|
|
* close themselves and don't do so within a reasonable amount of time, and
|
|
* therefore we always use the same callbacks. It's possible that we might
|
|
* use it for other things in future, or on the other hand we might decide
|
|
* that we're never going to do so and simplify it a bit.
