Return reasonable results for math.log(long) and math.log10(long) (we were
getting Infs, NaNs, or nonsense in 2.1 and before; in yesterday's CVS we

for positive arguments, no matter how large).

+- math.log and math.log10 now return sensible results for even huge
+  long arguments.  For example, math.log10(10 ** 10000) ~= 10000.0.

 - A new function, imp.lock_held(), returns 1 when the import lock is
   currently held.  See the docs for the imp module.
