[Zope-Checkins] CVS: Zope/lib/python/BTrees/tests - testSetOps.py:1.3

[Tim Peters]

Update of /cvs-repository/Zope/lib/python/BTrees/tests
In directory cvs.zope.org:/tmp/cvs-serv30763/tests

Modified Files:
	testSetOps.py 
Log Message:
testBigInput():  This spent almost all of its time building an IISet
from a sequence of ints in reverse-sorted order (a quadratic-time
proposition).  That doesn't test anything interesting in context, though.
So fiddled it to do a larger input, but it runs much faster now.
