Module Name:    src
Committed By:   drochner
Date:           Wed Jul 16 18:27:49 UTC 2008

Modified Files:
        src/sys/kern: tty_subr.c

Log Message:
wipe out tty buffer contents after read, to avoid keeping possibly
sensitive information in memory longer than necessary
(We could make this depend on ~ECHO or so, but this would be an API
change and I don't think it is worth the effort.)
