Also, I want to elaborate on the previous paragraph a bit more, in
case the motivation isn't clear.
The problem with TAP and KTAP as-is is that the name of a test case is
only known *after* it completes.
So the scenario being referred to is
KTAP version 1
1..1
<lots of output>
<kernel crash, no more output>
It would be nice if parsers could report "test FOO caused a crash" as
opposed to "the first test case caused a crash, good luck figuring out
which one that was"
