The initial api Filer api is edge triggered; that is, the act of opening a file in a round causes apt to assume the file will be finished writing that round. Apt does various forms of flushing to try to make sure the file contents are written out before the next round starts.

It would be a somewhat cleaner design to not attempt to process a file until the annotation processor had closed the file, indicating it was done with it. In this model, the registration would be two-phase.
