Component:  scipy.sparse  |     Version:  0.10.0

Comment(by pv):

 As far as I understand the situation, commit:8d749358 may already make the
 iterative inverses work in double precision (the input vectors are in
 double precision). However, the stuff on arpack.py:978 makes it pick the
 tolerance according to single precision.

 Changes, if any, should be made in IterOpInv.__init__

 I think this is again not a release blocker, we can again pick the test
 workaround from 0.10.1 if I don't manage to fix this in time...
