It seems that a Thread which is running a Fiber and that Fiber is blocked on a Queue#pop is unkillable via Thread#kill.

@headius mentioned that it should be possible to kill the Thread's current Fiber.
@dbussink wrote a rubyspec for this recently. rubinius/rubinius@9efac8a

This is somewhat related to the "Thread.current does not remain consistent between Fibers" bug.

I have been toying with killing all the Threads which are backing the Fibers.

Killing the Thread.current which is for the Fiber before killing the root Fiber's Thread allows the Thread to die.

Confirmed this is working in 9.x and 1.7.x is EOL. Resolving against a release so it shows up.
