I was a bit confused by the results until I realized gprof output only
includes CPU time. :-p

A question... is it possible to get profiling data that uses wall-clock
time instead of CPU time? It does not appear to be possible for gprof,
and I had a quick look and didn't find anything else like this.

For SQLite we're missing disk I/O, and for other SQL back-ends we'll
miss the time spent in another process...
