IIUC, the point of this patch is to avoid losing the journal after
a crash during the time when journal is idle. This seems like a
generally desirable property. So we should make it work (without
too much overhead) for the majority of
hardware/logging-intensity/power-saving-rules configurations,
and enable it by default.

On IRC Kay suggested 1-5 min. I think that this sounds about right.
Once the patch is in, I guess we can gather some statistics from
people and tune the settings.
