Huh. I learned two new Python facts this week:

1. print statements were slowing down my code enough to
really notice a particular transition. It went from about
2-3 seconds to a bit under 1 second. What at first seemed
unresponsive now seems almost snappy. The only difference
was removing a lot of print statements I had used for
debugging (Python 2.5, on a single core 1.97 Ghz machine).

2. Merely having a cPython decorator for profiling a 
function significantly slowed down performance...again,
from a about 2 seconds to just under a second (~1 second
doesn't seem much but these sorts of delays do affect 
user experience).  There is something ironic or 
Heisenbergian about that.
