Incidentally, this is a popular Oracle feature. It's a poor man's
"flashback" and similar to how some filesystems automatically create
regular snapshots of every home directory so you can get back stuff at
some arbitrary point in the past.
I haven't read the patch but are you delaying delivering the log or
delaying replaying it? I think you actually want the latter so in case
of a real failure you can choose between replaying the last 5 minutes
and recovering everything or intentionally dropping that history if
the failure was caused by an application problem.
