Since you are doing this in a webapp, you should be able to write a
WSGI middleware that enables the profiler if profile=true is passed as
query parameter.

I found this technique very useful to optimize webapps. Here is an example:

web.py has a nice profile middleware, it shouldn't be too hard to reuse it.
