Do I have the choice ? ;-)

Let's go:

 There are 2 parts in this change (1) do not test whether or not an
attribute is wanted to retrieve it and (2) make the retrieval of
arguments and other slots done separately. The rationale for (1) is to 
reduce the average size of the messages sent to the socket. The
rationale
for (2) is that since arguments slot can be very big, we still want to
be able to retrieve any slot without retrieving arguments; so we
retrieve that slot separately.
