Overall this looks very good! Two quick remarks:

Can you also augment the time_audit module? Next to
full_audit, it is another one where all functions should be
implemented.

The other one is in the implementation of the async engine.
You ordered the different _send, _done and _recv functions
so that you do not need prototypes. While this saves a few
lines, to me it is much easier to read if the functions are
lexically ordered according to their call sequence. First
the _send function, then the _done and after that the _recv
function. This makes the async flow almost as easy to read
as a non-async sequential flow. Can you change that? I know
there are examples in the code that do it differently, but I
think for new code we should adhere to this convention.

Thanks,

Volker
