  The last release of Grail uses binary pickles to store caches of
parsed bookmark files.  There are no floating point or NumPy objects
in the pickles, so that wouldn't test cases you may be interested in.
My choice to use binary pickles was entirely based on the performance
improvement; I doubt there are any substantial cross-platform issues
for bookmark files, especially when only used as caches!
