It's a good plan, but the devil is in the details.

next-error/previous-error might be a bit unreliable when there are other 
next-error-capable buffers around. And especially when the user has 
customized next-error-find-buffer-function. Anyway, you can try and see.

Also re. 4, if the buffer is not needed, you could probably use the 
fileloop package. It might need to be updated to behave "lazily", however.

If you want to work on such patch for the optional behavior, I'd be 
happy to review it.
