Where are the SOQL hits coming from?

Question

I've created an apex class that simply generates random data. we have created a sort of "checklist", similar to the todomvc project, which has checklist items and checklist assignees (contacts that are assigned to those todos). This class will generate both todos and randomly assign a list of contacts to the various tasks.

My question is, why am I getting hit by SOQL limits? generating 15 tasks puts the SOQL count up to 94/100. It doesn't seem to matter how many users I assign, so that isn't really upping the count. There should only be 5 SOQL hits (there is one not shown here in grabbing csv data from a static resource). All of the hits come when I upsert(tasks). I couldn't find anything about upserts affecting soql limits. Do they?

Can you help me figure out where the SOQL hits are coming from?

Thank you!

Set "PROFILING" to "FINEST" in your TraceFlag (Developer Console > Debug > Change Log Levels...), and it'll tell you where all those calls are coming from. Open the Developer Console, click on Debug, then Change Log Levels, then Click Add/Change on the General Trace Settings for You section, then create a new debug level with all values set to FINEST, then click the row to activate it, click Done, then change the expiration time to the future (it'll turn green), then click Done again.

In your logs, you'll see a CUMULATIVE_PROFILING_BEGIN area:
