/* If journalctl take a long time to process messages, and
* during that time journal file rotation occurs, a journalctl
* client will keep those rotated files open until it calls
* sd_journal_process(), which typically happens as a result
* of calling sd_journal_wait() below in the "following" case.
* By periodically calling sd_journal_process() during the
* processing loop we shrink the window of time a client
* instance has open file descriptors for rotated (deleted)
* journal files.
*
* FIXME: This change does not appear to solve the case of a
* "paused" output stream. If somebody is using `journalctl | less`
* and pauses the output, then without a background thread
* periodically listening for inotify delete events and cleaning
* up, journal logs will eventually stop flowing in cases where
* a journal client with enough open files causes the "free"
* disk space threshold to be crossed.
