Profiling iterators?

[Derek Chen-Becker]

Hi,
     I'm using Python 2.2 and a library that makes heavy use of 
iterators. I'm in the process of cleaning up/optimizing some of the code 
and I tried profiling it, but the profiler seems to completely ignore 
iterator calls, and even routines called by the iterator calls. Have I 
done something wrong, or is this a limitation of the profiler?

Thanks,

Derek
