These are serious concerns which involve various aspects of security.
If you need a response of your system within a given delay and
with high security, then I think you should avoid any OS at all and
rather program FPGAs.
In several cases you mentionned, like ballot, crashing the system
is not a big deal; which matters is to not deliver a wrong result.
Better crash than give a wrong result.
