A fix for the irreproducibility of the svds tests is in cset 20999:73f62b4bb533.  I wasn't 100% certain that this would not affect results in the field so I committed it to default rather than stable.  Marco Caliari is the author and if he has confidence that this won't interfere with existing code then we could easily backport the changeset.
