FYI, the current implementation in the distutils2-augmented pkgutil uses a cache (a function call memo) for functions that e.g. iterate over dist-info directories (and optionally egg-info directories too) or get a Distribution object representing an installed project. Tools that modify the state of the installation can call a function to clear this cache. A sqlite db would certainly speed things up; it could replace the existing caching in distutils2 or be left to other tools.
