Question...  For performance testing, I often code something like this:

1. Try to collect all the garbage I can.

2. Start the clock.

3. Run N iterations of the code in question.

4. Check the clock.

5. Do a final garbage collection to make sure I feel any remaining pain 
from garbage I've generated.

6. Check the clock again.

For steps #1 and #5, is calling "collect-garbage" three times the best I 
can do?
