and use it when passing possible-null-strings. It's still PITA but IMHO it looks a little better than doing it by hand.

I don't mind doing it by hand (and in some cases I prefer NOT having another layer of abstraction), but then we still need to have a way to (regularly) test for it.

Oh, and I figured fuzz testing on the Solaris buildbot would not be a good solution because only people with access to Solaris boxes would be able to reproduce the crash...
