A spawned task will start some time after you spawn it, and will finish some 
time later proportional to how much work it has to do.  Sounds like your spawn 
hasn't run to completion by the time you're doing your user query test.

You can use invoke if you want it to start right away and block til completed.

Or you can not worry about priming the pump.  On a production site with 
constant user load the priming you do won't matter since a user will be hitting 
the dictionary anyway.
