Now that I've finished the detour and committed and backpatched the 
changes to the way latency is calculated, we can get back to this patch. 
It needs to be rebased.

How should skipped transactions should be taken into account in the log 
file output, with and without aggregation? I assume we'll want to have 
some trace of skipped transactions in the logs.
