if the thing is sparse, memset could maybe be replaced by just setting
the non zero values to zero, in that sense many operationson on sparse
vectors can be done more efficiently than working on an array of zeros
with one non zero value, which if it applies here means you have to
rewrite the related code to be more efficient
