I tested this with the example provided by Jean-Claude DE SOZA.
It seems to work nicely but there was one figure that asymptote did not produce (figure 7).
The asy code for that figure needed a module geometry_dev which I don't have available.
Even though a final pdf was generated for the document as a whole, TeXShop was not showing it since Latexmk detected an error.

After commenting out the lines starting at the \begin{figure} to the corresponding \end for that figure (starts near or at line 93),
the example file compiled perfectly.

Made a small change and latexmk processed the whole thing in a flash.

Very nice.
