in general, closing a file flushes buffers to disk. So if you don't close it
and whatever medium the file is sitting on falls over, you will lose
whatever is in the unflushed buffers. In most file systems that I've worked
with you can explicitly flush the buffers.

But if you're sharing a file, and the file system knows how to deal with
sharing properly, then I would expect the file system (not the garbage
collector) to deal with all of that, rather in the way that the Rider
concept deals with things in the Oberon file system.
