Make gauss() semi-thread-safe. It can still give duplicate results,
...
but it can no longer raise an exception when called by several threads
simultaneously.

Correction to vonmisesvariate() by Magnus Kessler: it should take and
...
return something between 0 and 2*pi. Also added a reference to the
literature.

Fixed a bug in the gauss() function. The bug was reported by Mike
...
Miller, who complained that its kurtosis was bad, and then fixed by
Lambert Meertens (author of the original algorithm) who discovered
that the mathematical analysis leading to his solution was wrong, and
provided a corrected version. Mike then tested the fix and reported
that the kurtosis was now good.
