Thanks everybody for answers.

In my case, I don't need each and every scalar wiped out. In fact there is just this one type of data (credit card details) that I wish to handle securely.

Unfortunately, I don't see an option here. There are just too many places where raw data pass until they finaly reach my variables. (I'm using POE, with Wheels and Filters for I/O and credit card details are present in input and output messages in cleartext form (in one case over the IPsec VPN, and in other using UNIX socket to communicate to local process)).

As I see it now, there's not much hope in this case. Only real good kernel level security (eventualy, with secured swap space using loop-aes on Linux or something similar on *BSD), to reduce risks and try to make sure that in case of a break-in the damage will be minimal.
