Traditional PHP offers exactly this: the SAPI lifecycle tracks all file handles 
opened within a request, and closes them cleanly before reusing the thread or 
process for another request. Essentially what I'm proposing is a way to 
implement the same isolation in userland, by marking a checkpoint in the code.

As I've said repeatedly, it doesn't necessarily need to be a mandatory 
restriction, it can be a feature to help users write code without having to 
worry about *accidentally* leaving a background fiber running.
