An "inf float" can't be dumped in binary form.

[GCC 3.3.3 (SuSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more
information.
>>> import pickle
>>> import cPickle
>>> pickle.dumps (10e5000)
'Finf\n.'
>>> pickle.dumps (10e5000, pickle.HIGHEST_PROTOCOL)
Traceback (most recent call last):

This should work in CVS HEAD.
It's not very likely that it will get backported though.
