Comment (by zooko):

 It is bed time and unfortunately I haven't finished examining the patch in
 search of ways that it could make us write out ill-formatted SDMF files,
 or leak the write-authorization secrets, or succumb to an attacker's
 attempt to make us write out (and digitally sign) an SDMF file that we
 didn't mean to (including making us use a wrong sequence number). Those
 are the three possibilities that I consider to be the "worst case
 scenarios", so they are what I start looking for first. I'll resume
 looking for those possibilities tomorrow.
