 LS,

 I have just finished writing an implementation and test of a
 rolling_variance which I would be happy to contribute to the framework.

 It includes a redone version of rolling_mean which avoids potential
 overflow and accuracy issues. The rolling_variance currently returns zero
 when there are less than 2 samples available.

 I'd be happy to do assist to make this fit the accumulator framework
 better and I include a first draft of the code. Nothing spectacular, but I
 have not seen the 'rolling' version being published anywhere in the exact
 form needed, making this non-trivial to implement anyway.

 - Pieter
