> PerfLogger output is useful in understanding perf. There are large gaps in
> it, however, and it's not clear what is going on during these. Some sections
> are large and have no breakdown. It would be nice to add more stuff. At this
> point I'm not certain where exactly, whoever makes the patch (me?) will just
> need to look at the above gaps and fill them in.
