Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv21177/python/Lib/test
Modified Files:
	test_long.py 
Log Message:
Machines-- and Python --are a lot faster in relevant ways since this
test was written. So boosted the number of "digits" this generates, and
also beefed up the "* / divmod" test to tickle numbers big enough to
trigger the Karatsuba algorithm. It takes about 2 seconds now on my box.
