Actually there is no caching at all for smartcards.  Smartcards
usually don'tneed it because they "cache" the PIN's internally
(actually you use the PIN to get the card into another state and the
card's application mat or may not change that state.  The OpenPGP card
for example always changes it back to pin-required for the fist key,
unless you have changed that using the --card-edit:forcesig command.

However, I can see your problem.  As a solution I can only imagine to
add a special feature to allow for PIN caching. I'll think about this,
please give me til Monday and best watch the commit list.
