I don't see the similarity -- killing the buffer will kill the xwidgets,
while killing the buffer won't kill the process. On the other hand,
deleting text in a buffer won't make the process become unavailable.

There's nothing random about it. If the caller has marked the widgets
as being evaporable, then the caller wants those xwidgets to go away if
they're no longer displayed.
