Hi David,

I've attached a teachpack that makes collect-garbage available.  Save 
the file, open DrScheme, select Language > Add Teachpack ..., Add 
Teachpack to List... Navigate to the saved file and select it.  You 
should now be able to run your program.

DrScheme will implicitly collect values that are no longer in use during 
the running of your program so that their memory can be re-used (this 
process is called "garbage collection").  This process takes time, so in 
order for your timings to be more accurate, you should explicitly cause 
this process to happen just before collecting timing information.
