Logfiles are only removed when they are no longer needed. And they
are no longer needed when they hit their size boundary. So there is
always at least one logfile "live" in the repos. Further, if some
problem occured which necessitated recovery, a checkpoint is likely to
have been skipped, and that means that all the logs for the current
operation will still be left around (since no checkpoint means no
marking them as "no longer needed").
