[Python-Dev] Performance regression tests?

[Nick Bastin]

Does there exist a set of interpreter performance regressions tests?  
For example, I've modified the interpreter to allow the profiling of C 
extension functions, and want to make sure that the performance impact 
on non-profiled applications is negligible.  Does a test suite for this 
already exist (basically, something that calls a very lightweight C 
extension functions a few hundred thousand times)?
