Chip Salzenberg
explains why t/examples/japh.t keeps reporting "all tests successful" when
actually they're mostly segfaulting and otherwise failing.
This particular japh uses threading, which is known not to work until the
STM work by Charles Reiss (woggle) is merged.
I'm deferring this ticket appropriately.

> Wow. So I've just learned that our test harness ignores seg faults.
Nope. It's Test::* TODO magic. From t/examples/japh.t:
# known reasons for failure
my %todo = ( 1 => 'opcode "pack" is gone',
2 => 'opcode "pack" is gone',
4 => 'namespace has changed',
9 => 'P1 is no longer special',
10 => 'core dump',
...
Todo tests are run and supposed to fail or not to give the correct result, but
they are running ...

This *does* of course segfault.
