Update of /cvsroot/python/python/dist/src/Lib
In directory sc8-pr-cvs1:/tmp/cvs-serv20698/Lib

Modified Files:
      Tag: release23-maint
	random.py 
Log Message:
SF bug #778964:  bad seed in python 2.3 random

The default seed is time.time().
Multiplied by 256 before truncating so that fractional seconds are used.
This way, two consequetive calls to random.seed() are much more likely
to produce different sequences.
