#9770: SphericalDistribution() is not random
--------------------------+-------------------------------------------------

--------------------------+-------------------------------------------------
In the following list {{{l}}}, some elements repeat quite often:
{{{
sage: l = [ SphericalDistribution(dimension=2).get_random_element() for _
in range(1000)]
sage: uniq = []
sage: for x in l:
if x not in uniq:
uniq.append(x)
....:
sage: len(uniq)
34
}}}
The output is not random. For example, the first line is repeated ~30
times in the 1000 lines of output. It works fine if
!SphericalDistribution is only instantiated once!
