Some confusion seems to exist about the stats modules I'm writing. About a month and a bit ago I wrote hstats as a module to analyse hotshot profiling data. It was never my intention to make it compatible with pstats at all. It aimed at being usable to read profiling statistics from hotshot in an efficient way.

Currently I am working on the hpstats module, which will be api compatible with pstats. This module does use hstats so it only needs to handle higher level stuff. As an effect of this I'm now sometimes putting in new functionality into hstats but I hope this is a good thing.

So to say the essense again: hstats is not API compatible with pstats and is not meant to be.
