So that used to work. And note that if you take out the signal(SIGINT,
SIG_IGN) from the proglet, it will actually propagate the SIGINT and
work as expected.

So its only because perf handles SIGINT -- to be able to finish the
stat/data record, that it doesn't. Which is why I propagated the signal
the child got killed with.

Now apparently someone broke that again.
