Thanks! I pushed this with two changes -- one was to reword the docs a
bit more, and the other was to compute in_sample only if it's going to
be used (when exceeded is true). I hope this won't upset any compilers ...
I wonder if there's any sensible way to verify the behavior in an
automated fashion. Who know what marvels we'd discover about the
reliability/uniformity of random() across platforms.
