I'm going to test this later. Returning an error (or None in the case of next() should definitely be the default behavior.

Okay, I was able to reproduce this.
Do you want to work on a PR that adds something like a set_timeout(..) and a poll(..) method to the two stream implementations in src/io/{mmap, userptr}/stream.rs?
The next() method should then perform the polling and return None in case of timeout I think. I'm going to merge the next branch into master today or tomorrow, so I'd advise to start on top of that branch instead of the current master.

I had the same problem when using: https://github.com/loyd/rscam
With the changes here https://github.com/loyd/rscam/pull/32/files timeout can be added and also the pselect will return an error when the camera is unplugged.
