It's not a bug, but how xwidgets are designed, not unlike asynch
processes that have a buffer.
I find nothing wrong with this design of the xwidget system.
However, randomly killing xwidgets based on whether or not they are
displayed would be undesirable: xwidgets have a lot of state that cannot
be reconstituted through recreating them, and creating them takes a long
time and a lot of memory.

Nice, I'll start working on it. Thanks.
