Well let's get more data first on the costs of the flag
approach. If it's costly, then refusing it is clear.

If it's cheap, then we should look more carefully
at the flag approach because Simo's security arguments
are valid (IMHO).

Don't want extra complexity we have to pay for if
it's not going to be used, but marking memory as
'sensitive' does seem to be a feature that will get
used (as we handle security-sensitive data inside
Samba quite a bit).
