cache_pins solves the problem. enable that by default?

if we change code/config before release anyway, what should
we do with the max_send_size issue / related code?

currently I edit opensc.conf to set max_send_size to 255 for cryptoflex.
haven't tested if that breaks other cards. what would be a code equivalent?

/* Beware: the following needs to be a multiple of 4
 * or else sc_update_binary will not work on GPK */
/* increased to 256 on 2007-03-12 by aj so we have max size by default */
#define SC_APDU_CHOP_SIZE               256

and that size is used for both recv and send size. recv size needs to be at
least 256 AFAIK, so we can get a full 2048 byte signature in one apdu?

it also needs to be less for some readers, otherwise cryptoflex won't work in 
some readers. (ludovic mentioned the SCM readers can be fixed with a new 
firmware or the restriction can be ignored, but I need to search my old 
mails, what other readers had limitations too).

Regards, Andreas
