I agree. Also, there is something else that we all agree on: if one
mechanism can handle two problems with acceptable efficiency, it is a
mistake to introduce a second mechanism for the second problem.
So I pose the following test case:
Suppose C calls S, and S enters an infinite loop. How should the client
defend itself from this error? Notice that none of the "capability death
notice" ideas are helpful.
The only mechanism that I know about that can guard against this is some
form of watchdog (which is why I am backing away somewhat from my
earlier position about watchdogs).
If we conclude that we need watchdogs for this (or for something else),
then I suggest that kernel-supported capability death notice (any kind)
is unnecessary and should not be implemented.
