[Tex/LaTex] Bibliography spacing with BibLaTeX (and two columns)

biblatexmulticolspacing

I need to fine tune the distances marked as A, B, C and D in the figure below. Any suggestions?

In particular, I would like B=0pt, and the other three to be small.

I am using BibLaTeX and two columns:

\usepackage[backend=biber]{biblatex}
\usepackage{multicol}
...
\renewcommand{\bibfont}{\small}
\begin{multicols}{2}
    \printbibliography[heading=subbibliography]
\end{multicols}

For the sake of completeness: If one wanted to typeset the bibliography in two-column mode, but to leave the bibliography heading as a single column, here's how to do it:

\begin{multicols}{2}[\printbibheading]
\printbibliography[heading=none]
\end{multicols}
