New submission from steve21 <steve872929-bv at yahoo.com.au>:

$ python3.1
Python 3.1 (r31:73572, Jul  6 2009, 21:21:12) 
[GCC 4.4.0 20090506 (Red Hat 4.4.0-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import math
>>> math.log10(1000)
>>> math.log(1000, 10)

You would expect the results to be the same.
Internally math.log() could call math.log10() when base==10. That would
ensure they are consistent.
