This is exactly why it should be in the kernel once the developers can't
find any more bugs.  Marked as experimental, mainly, but in the kernel
where real users can throw cobol/Java/sql bastardizations at it and
break it.

Of course, I've worked on sufficiently few big projects that I'm still
naive enough to believe that unit tests _can_ catch everything, if
they're done right.  I'm sure I'll eventually be proven wrong...
